A payment address that invests part of every payment When you get paid, part of it is set aside for a US Stock Token you own and the rest stays spendable. You set the split once. Sleeve is live on Robinhood Chain mainnet at https://trysleeve.xyz. The problem People outside the US who are paid in digital dollars can already buy US Stock Tokens on Robinhood Chain. That starts with freelancers in Lagos. What they lack is a default. Every conversion is a fresh decision: open a wallet, pick a time, swap, check the price. Most paydays it gets put off. Research on retirement saving shows defaults outlast fresh decisions, and nobody paid in USDG has one. How it works 1. Share your Sleeve address. Payers send USDG on Robinhood Chain from any wallet and install nothing. 2. A payment arrives. Sleeve's keeper sees it and starts the split. If the keeper stops, anyone can start the split after a one-hour grace period. 3. Your rule splits it. The spend share stays USDG, and the equity share buys the Stock Token you picked. The suggested start is 90 percent spendable and 10 percent SPY. 4. It lands or it waits. If the market is open and the price is within your premium cap over Chainlink (1 percent by default), the Stock Token lands in your account. Otherwise the USDG waits in your account and buys after the open. You can release it to spend at any time. What is live on mainnet - Sign-up with a passkey or a wallet, into your own smart account. Sleeve never takes custody. - A split module that sorts only new income. Money already in the account, and USDG from your own actions in the app, is never split. - Four launch Stock Tokens: SPY, QQQ, NVDA and AAPL. Each one is checked against its Chainlink feed, an allowlisted Uniswap v3 pool and its market session before every buy. - A premium cap against the Chainlink price, measured from what actually left and entered your account, so pool fees can't hide. - A 25 USDG default minimum buy. Smaller amounts wait and add up. - Sell-back to USDG through the same price check (deployed, no mainnet sell yet). - A receipt for every split, written in the same transaction. Anyone can recompute it at https://trysleeve.xyz/verify, through a different RPC provider from the keeper's. - The issuer's disclosure word for word, with its hash on every receipt. Every holding is labelled: debt security, not a share. - Eligibility checks for the issuer's restricted and prohibited jurisdictions. Why Robinhood Chain Sleeve needs four things on one chain: issuer-backed Stock Tokens, native USDG, live Chainlink equity feeds and account abstraction. Robinhood Chain is where they meet. USDG is the income, the quote asset and the spend balance. Proof - Live app: https://trysleeve.xyz - Check a split: https://trysleeve.xyz/verify - Live receipts: https://trysleeve.xyz/receipts/1 to https://trysleeve.xyz/receipts/10. Ten mainnet payments on 4 October 2026, each split 0 to 5 seconds after it arrived and each matched by the verifier on the public RPC. The market was closed, so all ten are waiting for the open. - Price-discipline replay (provisional): across 1,000 replayed payments on real Robinhood Chain data, the guard refused a real mispricing at SPY's pool launch that buying at arrival would have paid, and in ordinary conditions waiting cost about 1.7 bps per payment. Provisional until a rerun on a second provider. https://github.com/winsznx/sleeve/blob/main/docs/HP2_RESULTS.md - Contracts on Blockscout: SleeveModule https://robinhoodchain.blockscout.com/address/0x15FA6775fCdB5904aA673967461dc1fA3c6E7Ac9 , with all seven contracts verified on Sourcify and listed at https://github.com/winsznx/sleeve/blob/main/docs/DEPLOYMENTS.md - Code: https://github.com/winsznx/sleeve What comes next - M1, 30 days: same-chain and cross-chain pay links, baskets, and borrowing against Stock Tokens once a Morpho market lends USDG against them. None of these is available yet. Also a hook-enforced daily key and an application to the Arbitrum Security Program. - M2, 60 days: the first payroll or invoicing integration, and 100 earners with at least two split paydays. - M3, 90 days: a fee decision, crews, and 1,000 earners, with retention reported from receipts.

Tiến độ hackathon

Built from scratch during the buildathon and live on Robinhood Chain mainnet at trysleeve.xyz. - Split module: income-only accounting, a market session check, a Chainlink-anchored premium cap, the waiting queue, release, sell-back and same-transaction receipts. 852 Foundry tests (unit, fork on mainnet state, audit and invariant), with 10,000-run fuzzing on the accounting invariants. Seven contracts deployed and verified on Sourcify. - Keeper on a VPS with a permissionless fallback, plus a verifier that rechecks receipts through a separate RPC provider. 1,681 TypeScript tests across the app, keeper, verifier and core. - App: passkey or wallet sign-up, the two sleeves, payments, holdings, rule and history, in light and dark themes. - Price-discipline replay on real Robinhood Chain data since 1 July: provisional, the guard refused a real mispricing at SPY's pool launch, and ordinary payments paid about 1.7 bps to wait. - Live payments: 10 payments to 2 accounts, each split within 5 seconds and verified, receipts at https://trysleeve.xyz/receipts/1 to /10. Weekend payments wait for Monday's open, and settling them writes a new receipt.
