All Chains

Suwappu supports 15 blockchain networks across three chain types: EVM, Solana, and non-EVM (Sui, TON). Every chain is accessible through the same unified API -- the chain parameter in your requests determines which network to use.

Using Chain Keys

Pass the key or alias as the chain parameter in API requests. Keys and aliases are interchangeable:

# These are equivalent
curl -X POST https://api.suwappu.bot/v1/agent/quote \
  -H "Authorization: Bearer suwappu_sk_..." \
  -H "Content-Type: application/json" \
  -d '{"from_token": "ETH", "to_token": "USDC", "amount": "1", "chain": "ethereum"}'

curl -X POST https://api.suwappu.bot/v1/agent/quote \
  -H "Authorization: Bearer suwappu_sk_..." \
  -H "Content-Type: application/json" \
  -d '{"from_token": "ETH", "to_token": "USDC", "amount": "1", "chain": "eth"}'

Currently Resolved Chains

The API currently resolves the following chain keys and aliases for swap routing:

Key	Alias
ethereum	eth
optimism	op
bsc	bnb
polygon	matic
arbitrum	arb
base	--
avalanche	avax
solana	sol

Additional chains (Fantom, Linea, Mantle, Gnosis, Scroll, Sui, TON) are live and queryable via GET /chains and GET /tokens, with swap routing expanding continuously.

Chain Types

EVM Chains

All 12 EVM chains share the same address format (0x...), use the same token standards (ERC-20), and are routed through the Li.Fi aggregator for optimal pricing. A single EVM managed wallet works across all EVM chains.

See EVM Chains for detailed token addresses.

Solana

Solana uses Base58 addresses, the SPL token standard, and routes swaps through the Jupiter aggregator. Solana wallets are separate from EVM wallets.

See Solana for token addresses and Solana-specific details.

Sui and TON

Sui uses the Move VM and TON uses its own virtual machine. Both have distinct address formats and token standards. Support for these chains is expanding.

Discovering Chains Programmatically

Use GET /chains to fetch all supported chains at runtime:

curl https://api.suwappu.bot/v1/agent/chains

Use GET /tokens?chain=<key> to fetch available tokens on a specific chain:

curl "https://api.suwappu.bot/v1/agent/tokens?chain=base" \
  -H "Authorization: Bearer suwappu_sk_your_api_key"
