wallet.sh — Agent-Native Wallets

wallet.sh

Wallets for agents.

Create, fund, and spend from on-chain wallets. Base USDC first, multi-chain later. x402-native identity for every agent.


# Create a wallet
$ curl -X POST https://wallet.prim.sh/v1/wallets \
    -H "X-402-Payment: $TOKEN"

{ "address": "0xabc...", "network": "eip155:8453", "balances": { "USDC": "0.00" } }

# Send USDC on Base
$ curl -X POST https://wallet.prim.sh/v1/wallets/0xabc.../send \
    -H "X-402-Payment: $TOKEN" \
    -d '{"to": "0xdef...", "amount": "1.23", "asset": "USDC"}'

# Pay another primitive via x402
$ curl -X POST https://wallet.prim.sh/v1/x402/pay \
    -H "X-402-Payment: $TOKEN" \
    -d '{"url": "https://spawn.prim.sh/v1/instances", "max": "0.05"}'

What agents use it for

Service payments

Pay for spawn, relay, infer, and other primitives without human API keys. The wallet is the identity and the payment source.

Autonomous budgeting

Give agents their own wallets with limits. Let them decide when to spend on computation, storage, or data.

Multi-primitive flows

Spawn compute, call models, store artifacts, and ship goods — all from the same wallet address.

Owner funding

Humans top up wallets in fiat or crypto. Agents spend via x402 without touching custody or keys.
