Chains And Funding

Seashail supports Solana plus a configurable set of EVM chains. Most tools accept a chain (or chains) argument that must match Seashail's configured chain identifiers.

Supported Chains (Default Config)

Solana:

• solana

EVM mainnets:

• ethereum
• base
• arbitrum
• optimism
• polygon
• bnb
• avalanche
• monad

EVM testnets:

• sepolia
• base-sepolia
• arbitrum-sepolia
• optimism-sepolia
• polygon-amoy
• bnb-testnet
• avalanche-fuji
• monad-testnet

Notes:

• The actual set of EVM chains is whatever is present in your config.toml under [rpc.evm_rpc_urls] and [rpc.evm_chain_ids].
• configure_rpc can change RPC URLs for existing configured chains. Adding a brand-new EVM chain requires editing config.toml (you need both RPC URL and chain id).

What Tools Work On Each Chain

The most reliable way to answer "what's available on my machine" is to call:

• get_capabilities

It returns a config-derived matrix of chains and supported surfaces (spot sends/swaps, NFT transfer, optional 1inch support, etc).

Quick Support Summary (Implemented Today)

Read-only tools (all configured chains):

• get_balance, get_portfolio, get_transaction_history
• get_token_price, inspect_token, estimate_gas

Spot writes:

• Solana (chain="solana"): send_transaction, swap_tokens (Jupiter), request_airdrop (devnet/testnet/local only)
• EVM chains (for example chain="base"): send_transaction, swap_tokens (Uniswap; optional 1inch when configured)

NFTs:

• Solana: get_nft_inventory, transfer_nft, plus marketplace envelopes (buy_nft, sell_nft, bid_nft)
• EVM: transfer_nft, plus marketplace envelopes (buy_nft, sell_nft, bid_nft)

Perps:

• hyperliquid: uses the wallet's EVM address
• jupiter_perps: uses the wallet's Solana address and requires Solana mainnet

Funding Wallets (Deposits)

Use:

• get_deposit_info

This returns:

• the deposit address for the selected wallet and account_index
• QR payloads (always includes a raw address; also includes EIP-681 for EVM)
• best-effort token hints if you pass token (for example token="usdc")

Example (Solana address + QR):

{
  "chain": "solana",
  "token": "usdc",
  "include_png": true,
  "include_ascii": true
}

Example (EVM address + EIP-681 payload):

{
  "chain": "base",
  "token": "native"
}

Safety notes:

• Only send assets on the same chain as the deposit address you requested.
• For EVM L2s, make sure the sender's wallet/network is set to the same L2 (for example Base vs Arbitrum).

Testnets: Faucets And Airdrops

Faucet links:

• get_testnet_faucet_links (informational, official URLs only)

Example:

{ "chain": "sepolia", "address": "0x..." }

Solana airdrops:

• request_airdrop (Solana devnet/testnet/local validator only; it is blocked on mainnet-beta)

Example:

{ "amount": "1.5", "amount_units": "ui" }
