托管交易

在 SatoriEx 上，下单和撤单无需任何费用，也不需要钱包签名。本页说明原因以及链上费用在哪里产生。

托管优先，按需上链

订单撮合、余额变更和结算均在 SatoriEx 内部运行——每笔交易无需 Polygon 链上交易。只有 SatoriEx 与外部钱包之间的充值和提现才涉及链上操作。

Coming from Polymarket?

Polymarket's "gasless" UX uses meta-transactions via Magic-deployed smart wallets — fills are matched off-chain, but settlement still touches the chain via the CTF, with the platform sponsoring the gas. SatoriEx is gasless for a fundamentally different reason: nothing about trading touches the chain at all. Matching, ledger debits/credits, and post-resolution payouts all happen inside SatoriEx's database. The chain is only involved on deposit and withdrawal. Practical impact: no relayer queue, no meta-tx delays, no per-fill gas, ever — but also no on-chain audit trail per trade.

下单时发生了什么

从您的角度来看，您调用一个 REST 接口并收到确认。在内部，SatoriEx 运行与托管转账相同的原子账本交易。

From the user's perspective: one HTTP call, one bearer token, one 202 Accepted. Matching and ledger updates happen asynchronously after the response; trade events arrive over WebSocket. No wallet pop-up, no signature, no chain transaction.

1. 客户端 → 携带 Bearer 令牌 POST /orders

2. 服务器验证 KYC 等级、权限范围、余额、市场状态

3. 202 Accepted returned immediately with an empty trades[] array — the match has not run yet

4. Matcher consumes the order from the queue and matches by price-time priority

5. Double-entry ledger atomically debits buyer / credits seller; the resulting trade event arrives over WebSocket

链上费用在哪里产生

任何跨越 SatoriEx 与外部钱包边界的操作都是真实的链上交易。

操作	用户成本	钱包签名
下单/成交/撤单	免费	无需
批量撤单	免费	无需
接收结算	免费	无需
从外部钱包充值	网络 Gas 费	需要
提现至外部钱包	网络 Gas 费	需要

SatoriEx 不对网络 Gas 费加价。链上费用是多少，您就支付多少。

权衡取舍

Custodial trading is fast and free, but it requires you to trust SatoriEx with funds in custody. A self-custody path — connect an external wallet, with fills matched off-chain by the CLOB engine and settlement crediting ERC-1155 conditional tokens via the CTF bridge — is planned (see Contracts and Changelog). Today, every fill settles on the SatoriEx ledger; only deposits and withdrawals touch the chain.
