Reference

Supported assets and networks

Everything below is read from this installation's asset registry. Status badges reflect what the operator has enabled, not a marketing claim.

Exact identifiers

The API takes exact identifiers such as USDT_TRON. Bare symbols like "USDT" are rejected because the same symbol exists on several networks.

Look-alike tokens are rejected

Only the issuer's canonical contract is accepted per network. Bridged "USDC.e" contracts are explicitly rejected: arbitrum-one: 0xff970a61a04b1ca14834a43f5de4533ebddb5cc8polygon-mainnet: 0x2791bca1f2de4661ed88a30c99a7a9449aa84174

Not offered

USDC on Tron is not offered. Native gas assets on Base, Arbitrum One and Polygon are provisioned for fee funding only and are not customer payment options.

Mainnets

Contract addresses were verified against issuer documentation and are fixed in code; operators cannot change them without a release.

Sandbox environment

Public testnets and simulated tokens

Where an issuer publishes no official testnet token (USDT on Sepolia and Nile), the sandbox uses a simulated contract that only the built-in simulator provider understands.

Reading the table

Confirmations is the number of blocks (or the finality rule, e.g. Tron "solidified", L2 "safe") required before a deposit counts. It is set per network by the operator within the registry's defaults.
Minimum deposit is the smallest amount that will be settled; smaller amounts are recorded and held.
Receive means addresses can be issued and deposits observed. Settle additionally means the signing provider and a fee wallet are configured so settlements can be sent. Both can be switched off by the operator during incidents.
The API (GET /assets, GET /fee-policy per asset, and the fee policy of every split session and splitter) reports network_cost_mode: separate_native_gas_budget for tokens: the gas of token transfers is paid in the network's coin from the platform's gas pool, and its estimated cost (every payout transfer, including the platform fee transfer) is charged as a network fee in the token before the split. For native coins it reports same_asset_execution_reserve: the estimated network cost is reserved from the deposit as a separate settlement line. See pricing.
