Agent-native, self-hosted trading infrastructure for crypto. Seamless OpenClaw integration.

Seashail is a local binary that exposes an MCP server over stdio. Agents can query balances, execute trades, and manage DeFi positions while Seashail enforces a policy engine and keeps key material encrypted at rest. The agent never sees private keys.

Features

• 60+ MCP tools — spot swaps, sends, bridging, DeFi (lending, staking, liquidity), perpetual futures, NFTs, prediction markets, pump.fun
• Policy engine — per-transaction and daily USD caps, slippage limits, leverage caps, allowlists, operation toggles, tiered approval (auto-approve / confirm / hard-block)
• Non-custodial key storage — Shamir 2-of-3 secret sharing for generated wallets, AES-256-GCM encryption for imported wallets, passphrase sessions with configurable TTL
• Multi-agent safe — proxy/daemon architecture lets multiple agents (Claude Desktop, Gemini, Codex, etc.) share one keystore and passphrase session without split-brain
• Multi-chain — Solana, Ethereum, Base, Arbitrum, Optimism, Polygon, BNB Chain, Avalanche, Monad, Bitcoin (+ configurable EVM chains and testnets)
• Agent-agnostic — works with any MCP-capable client; one-click templates for 10+ agents/editors
• Scam protection — optional signed scam-address blocklist, OFAC SDN checking, recipient/contract allowlists
• Verification — release assets signed with Sigstore Cosign, SBOM generation (SPDX-JSON)
