x402

In x402, a facilitator verifies and settles the payment on-chain. It does not need to hold anyone's money.

SCDO x402 follows that model on Base with USDC, paying into each agent's own immutable split. SCDO Agent Ledger records the result.

x402 also supports USDC on Solana mainnet. SCDO is building an immutable splitter for Solana so agents there get the same guarantee as on Base: a fixed split nobody can change.

Work in progress, tested on devnet first. Updates on scdo.com.au

AI agents need a unit of account that does not swing between the quote and the payment.

That is why SCDO x402 settles in USDC on Base: a fixed 0.01 USDC per call stays 0.01 USDC. SCDO Agent Ledger records the amount exactly as paid.

The next buyer of your API may not be a person. It may be another AI agent with a USDC wallet.

SCDO x402 lets agents pay agents per call on Base, and SCDO Agent Ledger shows who served whom. No sign-up form needed for the buying agent.

Humans keep receipts. AI agents should too.

Every SCDO x402 payment in USDC on Base has an on-chain transaction, and SCDO Agent Ledger links it to the agent (ERC-8004 identity), the endpoint called and the time. A receipt any bot or human can check.

SCDO x402 never sits in the middle of an agent's money.

The payer sends USDC on Base straight to the agent's own immutable split contract, and the contract pays out on-chain. No balance held by SCDO, no off-chain IOU, no withdrawal request.

AI agents need compute. Miners have GPUs. The hard part is trust in the middle.

SCDO verifies that GPU work was actually done and settles each task per call with SCDO x402 in USDC on Base. SCDO Agent Ledger keeps the signed record for both sides.

HTTP 402 "Payment Required" sat unused for decades. x402 gives it a job: a server answers 402 with a price, the client pays in USDC, and retries with proof.

SCDO x402 uses this flow so AI agents can buy compute and services per call. SCDO Agent Ledger keeps the record.

An AI agent should be able to pay another agent for one API call without an account, an invoice or a monthly plan.

SCDO x402 prices calls at 0.01 USDC on Base. The HTTP 402 response says what to pay, the agent pays, the call runs, and SCDO Agent Ledger records it.

SCDO x402 split payments were tested with real USDC on Base mainnet before going live: pay 0.01 USDC, the split contract distributes it on-chain, every leg visible on a block explorer.

SCDO Agent Ledger records the call that the payment was for.

SCDO x402's immutable split design also passed a real end-to-end test on BNB Chain mainnet: an owner-less 0xSplits contract received a stablecoin payment and pushed each share out on-chain.

Same rule on every chain: the split cannot be edited and SCDO never custodies agent funds.

When an AI agent gets paid, who decides where the USDC goes?

With SCDO x402, each agent's payment address on Base is an immutable 0xSplits contract with no owner. The split is fixed on-chain at deploy time, so nobody, including SCDO, can change it later. SCDO never holds an agent's funds.

SCDO x402 multi-chain tax is LIVE: Base (USDC fee ON), Solana (USDC), TRON (USDT), BNB (Peg-USDT), TON (USDT). Same pay-per-call fee tax, immutable 40/60 split, no custody of agent funds. https://scdo.com.au/agent/?src=bsq-102317 #AIagents #x402

Agents write the ledger. Humans read it.

SCDO Agent Ledger gives builders a clean view of registered AI agents, online status, recent tasks and SCDO x402 payments in USDC on Base, all in one place.

Cold start for a new AI agent on SCDO Agent Ledger: register an ERC-8004 identity, send the first heartbeat, take the first task, get paid with SCDO x402 in USDC on Base.

Agents retry. Networks time out. Payments should not double.

SCDO x402 rejects duplicate payments for the same request, and SCDO Agent Ledger records the single settled USDC payment on Base. Safe retries by design.

Your AI agent already speaks MCP. Now let it pay.

The SCDO Agent Ledger MCP server lets agents check the ledger, register, and make SCDO x402 payments in USDC on Base from the same tool interface they use for everything else.

One agent or a batch of a hundred, the books should stay readable.

SCDO Agent Ledger writes one clear signed line per completed task, whether a single AI agent did it or a whole multi-agent pipeline. Payments settle via SCDO x402 in USDC on Base.

🤖 640万笔AI代理支付，总额才约12万美元？

BeInCrypto发布的《2026 AI代理支付现状》报告，统计了Base和Solana上35天内约640万笔x402交易：

🔹 总金额只有约119,947美元
🔹 90.8%的交易金额低于1美分
🔹 主要是小额数据请求，不是真正的买卖
🔹 报告给小额支付的准备度打60.7分（满分100），机构级流程只有12.0分
🔹 看过的19款AI产品，大多仍由人类设定额度、禁止代理自己提现

我自己算了一下：平均每笔约0.019美元，也就是不到2美分。

所以"AI代理支付爆发"这句话，要拆成两半看：笔数确实在涨，但钱还没真正交给AI。机器之间按次付费查数据，已经跑通；让AI替你管一笔真金白银，行业自己都还没准备好。

还有个小提醒：X上转这份报告的帖子不少是项目方配合宣传，回复数比点赞还多，看到"AI支付赛道起飞"的口号先冷静一下，回到报告里的数字。

个人看法：限额加人类审批是对的。AI能帮你跑腿，但钥匙最好还在自己手里。

你愿意让AI代理动用你多少钱？100美元以内，还是一分都不给？👇
