Specifying a Token
A token in the API is always identified by two fields together: achain and a token_id. Both are required in every quote and swap request.
chain— for Bitcoin variants this is a named string ("Lightning","Arkade","Bitcoin"); for EVM tokens it’s the chain ID as a string ("1"for Ethereum,"137"for Polygon,"42161"for Arbitrum).token_id— for Bitcoin variants this is always the literal string"btc"; for EVM tokens it’s the ERC-20 contract address.
Asset that bundle both fields:
Asset objects directly with client.createSwap({ source, target, ... }). For client.getQuote(...) pass the four fields separately (see example below).
Supported Tokens
Bitcoin
For all three BTC variantstoken_id is always "btc". The chain distinguishes the variant.
EVM Chains (HTLC + CCTP source/destination)
For EVM tokens,chain is the chain ID as a string and token_id is the ERC-20 contract address.
Common token contract addresses on these chains:
Any other ERC-20 on these three chains is also supported via DEX aggregation — see Dynamic EVM Tokens below.

Bridge-Only Chains
Satora bridges to the target chain via two protocols depending on the target token:- USDC is bridged via Circle CCTP
- USDT is bridged via LayerZero USDT0 OFT (Omnichain Fungible Token)
USDC Bridge Chains (via CCTP)
Swap BTC to USDC on any of these chains.USDT Bridge Chains (via LayerZero USDT0)
Swap BTC to USDT on any of these chains.Dynamic EVM Tokens
Satora Swaps supports a changing list of tokens on Polygon, Ethereum, and Arbitrum via DEX aggregation. Any ERC-20 token available on a DEX is usable as a source or target for swaps. Retrieve all available tokens:Available Swap Directions

Gasless claiming on all EVM chains - Satora covers gas fees on Polygon, Ethereum, and Arbitrum via EIP-712 signature-based claiming. A small gas fee is deducted from the swap amount depending on network conditions. Alternatively, you can claim manually with your own wallet and pay gas yourself.
