$EDSD — Settlement Stablecoin

What $EDSD is

$EDSD is a USD-pegged stablecoin designed for one job: settlement of cross-border trade on EDMA L2. It is not a general-purpose payment token, it is not a yield-bearing instrument, it is not an algorithmic peg. It is fully USD-backed at one-to-one, issued by a regulated issuer entity under applicable U.S. financial regulations, and used as the default settlement currency in the TradeOS marketplace.

The narrowness of the design is structural. Settlement currencies need three properties: stability of unit, transparency of backing, and programmability for milestone-based release. Bank-issued dollars have stability and (with audit) transparency, but not programmability. Algorithmic stablecoins have programmability but neither stable backing nor verifiable reserves. Existing USD-backed stablecoins have all three but are not integrated with the PoV milestone-gate settlement model that EDMA's protocol requires. $EDSD was built to fill the gap.

FOUR LAYERS, ONE PEG

The $EDSD stablecoin maintains its USD peg through a fully-backed reserves model with on-chain transparency. Every dollar of $EDSD in circulation is backed by one dollar of off-chain reserves attested by independent auditors. The four-layer architecture makes the backing verifiable rather than trusting an issuer's claim.

USD Reservescash and short-term treasuries

100 percent USD-denominated reserves held in segregated accounts at qualified institutional custodians. Composition targets approximately 80 percent short-term US Treasury bills (under 90 days), 20 percent cash equivalents in FDIC-insured bank deposits. No commercial paper, no exotic securities, no rehypothecation. Reserves are bankruptcy-remote from the issuer, meaning if the issuer fails, the reserves remain available to redeem outstanding $EDSD rather than being claimed by the issuer's creditors.

Issuer InfrastructureRegulated issuer, multi-jurisdiction

The issuer is a regulated entity operating under applicable U.S. financial regulations, with the design pursuing equivalent regulatory authority in the European Union (under MiCA) and Singapore (under MAS). Monthly attestations are signed by independent CPA firms chosen from the top five audit firms; quarterly full audits include the reserve composition, the mint-and-burn ledger, and the on-chain supply reconciliation. Reserves and supply are published in real time on a public dashboard, with attestation reports archived for at least seven years.

Mint and Burn ContractsThe peg engine

Mint operations require verified deposit of USD reserves at the custodian; the custodian's confirmation is signed and submitted to the on-chain contract, which then mints the corresponding $EDSD to the depositor's address. Burn operations work in reverse: $EDSD is sent to the burn function, the contract releases the reserves at the custodian to the redeemer's bank account. Mint and burn are atomic and verifiable on Ethereum mainnet (anchored from EDMA L2). There is no fractional reserve, no algorithmic peg, no rebasing. The peg holds because the backing is one-to-one and the smart contract enforces the constraint.

Settlement Integrationreplaces LCs in cross-border trade

$EDSD is the default settlement currency in TradeOS marketplace. Buyers escrow $EDSD at milestone gates of a cross-border trade contract; releases are PoV-verified by attestor consensus rather than by bank correspondence. This structural change replaces the Letter of Credit workflow, which traditionally locks 50 to 500 thousand dollars per transaction for 60 to 180 days at 1.5 to 3 percent per annum, requires correspondent banking relationships, and generates paper documents at each step.

The four layers are independent. Reserve attestation is not taken on faith from the issuer; it is signed by independent auditors. Smart contract enforcement is not trust in the team; it is on-chain code. Settlement integration is not a single integration choice; it is the protocol default. The peg holds because the backing is verifiable at each layer, not because the issuer asserts it.

The four-layer backing architecture. Reserves are held at qualified institutional custodians, bankruptcy-remote from the issuer. The issuer operates under applicable U.S. financial regulations, with the design specifying monthly attestations and quarterly audits. The mint and burn contracts (the boundary layer, the peg engine) enforce one-to-one issuance and redemption on-chain. The settlement integration uses $EDSD as the default currency for TradeOS milestone-gate trades.

Why $EDSD replaces Letters of Credit

The Letter of Credit is a nineteenth-century instrument that solved a real problem: when buyer and seller cannot trust each other and cannot trust their local banks to handle a cross-border payment, an intermediary bank stands between them, holds the buyer's money, and releases it only when documents prove the goods shipped. The mechanism works, but it is expensive (1.5 to 3 percent per annum on the LC value), slow (60 to 180 day settlement windows are common), and paperwork-intensive (each milestone requires a paper document chain across customs, financiers, freight forwarders, and banks).

$EDSD with smart-contract milestone gates does what LCs do for a fraction of the cost and an order of magnitude faster. The buyer escrows $EDSD in a trade contract; the smart contract releases it only when PoV-verified evidence of milestones (bill of lading, customs clearance, attestor consensus) arrives on-chain. The buyer cannot revoke; the seller cannot prematurely claim; the smart contract enforces the wait. The Letter of Credit's structural role of guaranteeing that the wrong party does not get the money is preserved, but the cost structure, the latency, and the paper trail are replaced.

REPLACING LETTERS OF CREDIT, ONE TRADE AT A TIME

A traditional cross-border trade pays 1.5 to 3 percent per annum for a Letter of Credit, locks 50 to 500 thousand dollars in escrow for 60 to 180 days, and accrues paperwork friction across customs, financiers, and inspectors. The same trade settled with $EDSD on PoV consensus pays an order of magnitude less, takes hours instead of months, and produces a verifiable on-chain record at every milestone.

S1Marketplace Match

A buyer commits to a trade on TradeOS by depositing $EDSD into the trade contract. The deposit triggers the trade lifecycle; the buyer's $EDSD is now in escrow controlled by the smart contract, not by the buyer, not by the seller, not by any correspondent bank.

S2Milestone Gate 1

The contract holds the $EDSD until the first milestone evidence is submitted (typically: shipping documents, bill of lading, customs clearance). Until that evidence arrives and verifies, no party can withdraw the funds. The buyer cannot revoke, the seller cannot prematurely claim, the smart contract enforces the wait.

S3Evidence Submission

The seller submits proof of shipment: the bill of lading from the carrier, customs clearance documents, and a PoV-signed timestamp from one or more registered attestors (port authorities, customs agents, freight forwarders). Each submission is cryptographically signed and stored on-chain.

S4PoV Verification

Attestor consensus is reached: a quorum of registered attestors (typically 3 of 5 or 5 of 7 depending on the trade tier) signs the evidence as valid. The cryptographic proof is verifiable by any party; the consensus is recorded on EDMA L2 and anchored to Ethereum mainnet.

S5Milestone Release

Once verification reaches consensus, the contract executes the milestone release automatically. $EDSD is transferred from escrow to the seller's wallet. The seller can immediately burn it to USD at the issuer's redemption window or hold it as a stablecoin balance. No bank intermediary, no settlement delay, no foreign exchange spread.

S6Settlement Anchoring

A settlement receipt is anchored to Ethereum mainnet, creating a permanent record of the trade: parties, value, milestones, attestors, timestamps. The receipt is auditable by any party (tax authorities, regulators, financiers, the parties themselves) for the entire lifetime of the chain.

At each milestone, $EDSD release is gated by verifiable evidence. The buyer does not trust the seller; the seller does not trust the buyer; both trust the smart contract that enforces conditions only it can verify. The Letter of Credit's role — guaranteeing that the wrong party does not get the money — is structurally redundant when the gate enforcement is on-chain and the consensus is cryptographic.

Settlement flow replacing Letters of Credit. The buyer commits $EDSD, the smart contract escrows it at milestone gate one, evidence is submitted and PoV-verified by attestor consensus, the contract releases $EDSD to the seller, and the settlement is anchored to Ethereum mainnet. The full flow runs in hours; the traditional LC equivalent runs in 60 to 180 days at 1.5 to 3 percent per annum cost.

Backing and transparency

The peg is maintained by full off-chain reserves at regulated custodians. The current reserve composition is 80 percent short-term US Treasury bills (maturities under 90 days), 20 percent cash equivalents in FDIC-insured deposit accounts. The reserves are held at qualified institutional custodians in segregated accounts that are bankruptcy-remote from the issuer entity; if the issuer fails, the reserves remain available to redeem outstanding $EDSD rather than entering the issuer's bankruptcy estate.

Transparency is enforced through three layers. Monthly attestations from independent CPA firms (chosen from the top five audit firms) verify the reserve composition matches the on-chain supply. Quarterly full audits review the mint and burn ledger, the reserve composition, and the on-chain supply reconciliation. A real-time public dashboard publishes the current reserves and the current $EDSD supply, with attestation reports archived for at least seven years. The combination means a holder of $EDSD does not need to trust the issuer's assertion alone; the assertion is independently verified at three layers and on a continuous cadence.

Use cases beyond settlement

$EDSD is the settlement default in TradeOS, but the same stability and programmability make it useful in adjacent contexts on EDMA L2. The Paymaster routes user gas payments through $EDSD so end users transact on EDMA without holding $EDM directly; the conversion happens at the protocol level invisibly. The DeFi layer (lending, structured finance, liquidity provision) uses $EDSD as a stable unit of account for collateral valuation and yield calculation. The marketplace's institutional-tier trades quote prices in $EDSD because the unit needs to be stable for institutional pricing models.

What $EDSD is not: it is not a yield-bearing stablecoin, it is not a synthetic asset, it is not lent out to generate the reserve composition's yield. The reserve yield (which exists, given the Treasury bill composition) accrues to the issuer entity and is used to operate the issuer infrastructure. Holders of $EDSD receive a stable USD-equivalent token, not a share of the reserve yield; the design is intentional to keep the legal classification simple (a payment stablecoin, not a security) and to keep the peg mechanism trivially verifiable.
