wallet

Multi-chain wallet operations for EVM and Solana with balance queries, transfers, signing, and transaction history. Multi-chain wallet for EVM (DeBank-supported chains) + Solana. Balances, transfers, signing, policy management. ⚠️ DENY > ALLOW in Privy. DENY * overrides ALL ALLOW rules. NEVER mix them. - Supports 13 tools across EVM (Ethereum, Base, Arbitrum, Optimism, Polygon, Linea) and Solana, including balance checks, fund transfers, message signing, and transaction history - Use wallet_get_all_balances() for complete portfolio visibility across all chains with USD values in a single call - Transfers are policy-gated by Privy TEE — only whitelisted addresses and amounts within daily limits are allowed, even if the agent is compromised - Includes EIP-712 typed data signing for permits and off-chain orders, plus transaction pre-signing without broadcasting for multi-step workflows - Authentication is automatic via Fly OIDC token; no API keys or manual wallet address entry needed - Gas is sponsored by default on EVM chains — user doesn't need native tokens for gas. Falls back to user-paid if sponsorship is unavailable. Use sponsor=false in wallet_transfer to explicitly pay gas from wallet balance.
