What this page covers
Every value movement on EDMA pays a known protocol fee. This page lists the canonical fee schedule across all five transaction types (certificates, trade milestones, supplier payments, FX off-ramps, gas), explains the per-tranche caps that limit absolute fee exposure on large trades, and describes how the fee revenue is split between $EDM burn and the treasury at the contract level the moment a transaction proves out.
The fee schedule is enforced on-chain by the Fee contract. Published rates apply uniformly to every participant; the only optional variables are tier-band discounts on supplier sends and standard governance-set parameter changes (subject to 72-hour timelock and rate-limited adjustments). For the downstream split mechanics see Split; for per-shipment revenue math see Unit economics; for the demand drivers that scale this flow see Demand drivers.
Per-transaction breakdown
Certificates (Carbon, REC, GO) settle at 4 percent total, split 2 percent to the seller and 2 percent to the buyer. The symmetric split matches established market convention and prevents either side from bearing asymmetric fee burden. A 2,500 tCO2e retirement at $40 per tonne yields $4,000 platform revenue ($1.60 per credit). REC/GO math is identical because the protocol is unit-agnostic: 10,000 MWh at $15 per MWh yields $6,000.
Trade milestones pay 0.5 percent of each released tranche, capped per-tranche to limit absolute fee exposure at scale. A $1.5M CIF shipment on a 20/60/20 milestone schedule generates $7,500 in milestone fees total ($1,500 on M1, $4,500 on M2, $1,500 on M3). With a 45-day M1 dwell at 5 percent APY, the Treasury Interest line adds $1,875 to the receipt. Caps engage at tranches above $1M; see the cap tiers below.
Supplier sends charge 1 percent to the initiator on intra-platform $EDSD B2B payments. The fee scales linearly with send amount and applies to every send regardless of size; banded discounts and pre-purchased send blocks lower the effective rate for network programs and high-volume corridors. A $250,000 send at the standard rate generates $2,500; at a 0.80% program band it generates $2,000.
FX off-ramps charge 25–40 basis points on fiat exits as a published spread, plus pass-through third-party costs (custody, Travel-Rule compliance, banking rail fees) line-itemized on the receipt. EDMA does not mark up third-party fees; the published spread is the protocol's share. A $400,000 off-ramp at 30 bps yields $1,200.
Gas is not a fee. The Paymaster auto-pays gas in $EDM or $EDSD at tiny per-transaction cost; users do not need to hold ETH. Gas is not subject to the 50/50 burn split and never deducts from the burn half of protocol fees.
Caps, discounts, and rebates
Per-tranche caps on trade milestones bound the absolute fee at each tier. Without the cap, a $50M tranche would generate $250,000 in fees at the base rate; with the $25,000 cap, large institutional shipments stay competitive with letters of credit at sovereign scale. The cap engages above $1M (where 0.5 percent equals exactly $5,000), above $2.5M (where 0.5 percent exceeds the $12.5k tier-2 cap), and above $5M (where 0.5 percent exceeds the $25k tier-3 cap).
Supplier send discounts are negotiated network-program-by-program: a high-volume corridor with hundreds of suppliers can pre-purchase send blocks at a 0.20% to 0.40% discount off the standard 1% rate, lowering the effective rate to 0.60–0.80% for the duration of the prepaid block. Beyond block discounts, supplier programs can graduate to lower published tiers as active supplier count and monthly send volume cross threshold metrics defined in the program kit.
Rebates on protocol fees apply only to the treasury half of the 50/50 split. The burn half is sacrosanct: no rebate, discount, or governance action can reduce the 50 percent of every protocol fee that destroys $EDM at the moment of settlement. This constraint is contract-enforced and non-votable. The treasury half can fund rebates, but only within governance-set bounds and never retroactively (rebate parameters apply forward-only from the effective_from timestamp).
Burns and treasury
Every protocol fee splits 50/50 between burn and treasury at the contract level the moment a transaction proves out. The burn half is destroyed in $EDM immediately and the burn transaction hash lands on the receipt and proof page. If the fee was prepaid in $EDSD or USD, the burn half is converted to $EDM at the release block before being burned. The treasury half routes on-chain to the TreasurySplitter and splits across five governance-controlled buckets: Attestors (40% default, SLA-weighted by latency and accuracy), Network ops (25%), Builders (20%, grants for SDKs and tooling), Ecosystem (10%), and Stakers (5%, veEDM epoch rewards).
Each Friday at 00:00 UTC, an additional buyback-and-burn cycle uses 50 percent of net protocol fees from the prior week to repurchase $EDM from the open market and burn the repurchased tokens. The DAO may adjust the buyback ratio by ±10 percent per quarter with supermajority approval. The combined effect drives the long-term supply curve from 500 million toward a 100 million $EDM target, ensuring deflationary economics directly tied to network use rather than to a fixed burn schedule. For the full split allocation across the five buckets, see the Split page.
