Onchain Agent Wallets

io.github.nirholas/onchain-agent-walletsv0.1.0Other

Give an AI agent a Solana spending allowance instead of your key. Chain-enforced cap, x402.

The current version, v0.1.0, was published to the official MCP registry on 2026-08-19. It is distributed as @three-ws/onchain-agent-wallets on npm, filed under Other by this index, and declares 5 environment variables. Removals and unreachable sources are measured across every server this index tracks, contract drift across the servers that answer in consecutive snapshots; the index's current counts put this record in context.

In-path gate · all MCP tools

Using Onchain Agent Wallets in Claude, Cursor, Gemini CLI, Cline, or Zed?

MCP tool contracts can change remotely with no version bump. The mcpindex gate pins each contract and HOLDs the call when it drifts-before your agent acts. Zero credentials. This is not the package install for this server itself (use Install this server for that).

Install the mcpindex gate (one command)

Rewrites your MCP host config so each server launches behind the gate. Inspect first: curl -fsSL https://mcpindex.ai/install.sh | less

Trust verdict · v1 advisory · method
NOT YET SCREENEDno verdict on file

Verdict not yet evaluated for this tool. The semantic screen takes adversarial cases first; coverage rolls out as the corpus expands (15/150 labels to graduation). The deterministic conformance probe is built but has not yet run on the public corpus, so a recorded verdict here is REVIEW or UNVERIFIED, never a clearing ALLOW. Until a verdict is recorded, an agent should treat this tool as not-yet-cleared and fall back to its own checks. Method: the eval, four-state verdict, honest limits.

That verdict was true at screening time (snapshot 2026-08-20).

Contracts can change after screening, with no version bump. The gate pins Onchain Agent Wallets’s tool contracts on first sight and holds any silent change before your agent acts - the check that keeps being true on Tuesday.

Environment variables
OWNER_SECRET_KEY
secret

Owner secret key, base58 or a JSON byte array. Optional: without it every owner action is returned as an unsigned transaction for Phantom, Solflare, Backpack, or a Ledger to sign.

OAW_NETWORK

Cluster: mainnet or devnet. Defaults to mainnet. State is kept per network, so a devnet rehearsal never touches mainnet agents.

SOLANA_RPC_URL

HTTPS Solana RPC endpoint. Defaults to the public endpoint for the configured network; bring your own (Helius / Quicknode / Triton) for production.

OAW_STATE_DIR

Where agent keypairs, guardrails, and the spend ledger are stored. Defaults to ~/.onchain-agent-wallets, written 0600 inside a 0700 directory.

REQUIRE_CONFIRM

Refuse to broadcast anything that moves value until the call is re-issued with confirm:true. Default true.
