託管交易
在 SatoriEx 上，下委託和取消委託免費且無需錢包簽名。本頁說明原因，以及鏈上成本在哪裡確實存在。
優先託管，需要時上鏈
委託撮合、餘額變更及清算在 SatoriEx 內部執行——每筆交易無需 Polygon 交易。只有 SatoriEx 與外部錢包之間的儲值和提領才接觸鏈。
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.
下委託時發生的事
從您的角度來看，您呼叫一個 REST 端點並收到確認。在內部，SatoriEx 執行與託管轉帳相同的原子帳本交易。
1. 客戶端 → 帶 Bearer Token 的 POST /orders
2. 伺服器驗證 KYC 等級、範圍、餘額、市場狀態
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
鏈上成本確實存在的地方
任何跨越 SatoriEx 與外部錢包邊界的操作都是真實的鏈上交易。
| 操作 | 使用者成本 | 錢包簽名 |
|---|---|---|
| 下委託／成交／取消委託 | 免費 | 無 |
| 批量取消 | 免費 | 無 |
| 收取清算款項 | 免費 | 無 |
| 從外部錢包儲值 | 網路 Gas 費 | 需要 |
| 提領至外部錢包 | 網路 Gas 費 | 需要 |
SatoriEx 不對網路 Gas 費加成。鏈上成本多少您就付多少。
取捨
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.
