Celo Sepolia and Tron Shasta are used as a running example across the Settle payments guides — a starting point, not a limit. Atum supports many additional EVM networks, plus Solana, with more chains on the way. See Supported networks for the full gateway list. The reference agent template ships preconfigured for the Celo Sepolia ↔ Tron Shasta corridor. The EVM plugin can point at any supported EVM testnet, and additional corridors can be enabled — email support@atum.xyz to enable networks beyond the template defaults. The tables below list the generally supported source-deposit tokens on each testnet, not every token /v1/defaults returns. That endpoint is still the authoritative live allowlist — a token absent there cannot be deposited, whatever this page says. Tempo Moderato (eip155:42431) is omitted here because its corridors are access-gated. Tron Shasta USDC is still served by the gateway and omitted here because USDC on Tron is no longer officially supported.

Assets

Asset identifiers follow the CAIP-19 standard — use them when configuring a settler agent. All testnet assets below use 6 decimals.
A ticker is not a unique identifier. The same symbol maps to different tokens on different chains, and a single chain can host multiple versions of the “same” asset — native vs. bridged or wrapped (e.g. Polygon’s native USDC and bridged USDC.e are distinct tokens). Always identify an asset by its full CAIP-19 string, never by ticker. See Supported assets for the exact identifier on each chain.
