Context Cost
This is the approximate number of tokens consumed each time the server's tools are loaded into a model's context. Higher counts reduce the attention available for other tasks.

🟢request_verification_challenge(address, agent_id, chain)
Step 1 of wallet verification: get a fresh challenge for the user to sign. chain: "evm" or "solana". Pass agent_id (your marketplace identity) so the proof is bound to you. Present `challenge` to the user, have their wallet sign it (EVM personal_sign / Solana signMessage), then call verify_wallet_ownership with the returned `nonce` + signature. The challenge is single-use and expires (~10 min). Returns {challenge, nonce, expires_at}.

}🟢verify_wallet_ownership(address, signature, nonce, chain, agent_id)
Step 2 of wallet verification: prove control by signing the challenge from step 1. chain: "evm" (secp256k1, 0x-hex signature) or "solana" (ed25519, base58/base64/hex). `nonce` is from request_verification_challenge; the signature must be over that exact challenge text. Pass the same agent_id you requested the challenge with — on success the wallet is linked to you and you get a session_token to pass to Tachyo's other agents (e.g. check_token_safety) to unlock connected/premium tiers. Returns {verified, address, chain, linked, session_token?, session_expires?}. Does not move funds or expose keys.
