The same underlying token across chains and wrappers maps to one Tplus asset: USDC and USDT credit as USD; ETH on Ethereum, Arbitrum, Monad, and Base credits as ETH; cbBTC and wBTC credit as BTC. Trading and collateral use the unified asset; per-chain vault balances are kept in line by rebalancing. The asset registry is served by GET /registry/assets. A pooled balance is identified by its Tplus asset index, Index(n). A balance that is not pooled is identified by its chain-specific token address, Address(token@chain), and trades as an isolated, chain-specific asset.

Production EVM chain set

Production asset-config rows currently use this EVM chain set. Supported tokens vary by chain; use GET /registry/assets for per-asset availability. For confirmation policy and approximate wait time, see Deposits.

Deposit caps and isolation

Each (asset, chain) pair has a total deposit cap and a rolling 1-hour deposit cap (asset parameters). A deposit that breaches a cap is still credited, but as an isolated Address(token@chain) balance that is not fungible with the pooled asset and cannot be used for leverage until caps allow.
Example: if the rolling 1-hour deposits for Arbitrum USDC are 95,000 USDC, max1hrDeposits = 100,000 USDC, and a user deposits 10,000 USDC, then rolling_1h_after = 105,000 USDC. The deposit is credited as isolated Address(token@chain) balance instead of pooled Index(USD). Isolation is not permanent. As cap capacity frees up - the rolling 1-hour window ages out, or total deposits fall back below maxDeposits - isolated balances are promoted back into the pooled Index(n) asset. Promotion is automatic, applied on the account’s next deposit or withdrawal of that asset, and fills only the headroom currently available, so a large isolated balance converts in steps as capacity allows. Continuing the example: once the earlier deposits age out of the 1-hour window, the isolated 10,000 USDC is promoted to pooled Index(USD) on the account’s next deposit or withdrawal - partially if only some headroom has reopened, fully once there is room for all of it.
