| What it is | Status | Look at | |
|---|---|---|---|
| Cryppit | My company: keyless, read-only tools for cross-chain money, and research into autonomous agents. | Active | github.com/cryppit |
| Where's My Swap | Paste a NEAR Intents order and see every hop to its payout, where the money is now and who can move it. Checks payouts on 33 chains and flags order accounts locked by NEAR Intents' operators. Its address check says, before you send, whether your wallet can pay an address on all 21 chains NEAR Intents pays out to. Free, no keys, no sign-in. | Live | the checker · address check · ZEC route |
| Where's My Withdrawal | Paste a rollup withdrawal and see which step is missing and who can finish it, across 13 chains: the OP Stack chains, Blast, Arbitrum One, Robinhood Chain, Linea and ZKsync Era. It prints the exact call, and anyone may send it. Read-only, no keys. | Live | repo · page |
| Safe to Send | Paste an address and the chain you are sending on: see whether funds sent there can be reached, before you send. Reads 20 chains and catches smart wallets that only exist on one chain, with an archive of all 4.25M Abstract wallets that keeps working after Abstract shuts down on 15 Dec 2026. Read-only, no keys. | Live (26 Oct 2026) | page · repo |
| NU7 Readiness | Which Zcash wallets, libraries, bridges and swaps are ready for NU7, from public evidence (GitHub issues, PRs, releases, source). Read-only, re-checked hourly. | Live | board · repo |
| Shield Receipt | Paste a ZEC withdrawal's txid and the address you gave: see whether the exchange paid the transparent part or it landed shielded, and in which pool (Sapling, Orchard or Ironwood). Only the txid is sent; the address stays in your browser. Read-only, no keys. | Live (31 Oct 2026) | page · repo |
| Zcash Refund Helper | Finds a ZEC or BTC deposit stuck in the NEAR Omni bridge and prints the bridge's own refund steps. Read-only: it never holds keys or signs. 213 tests, MIT, ZECATHON 2026 entry. Used on mainnet on 15 Oct 2026 to return a stuck deposit to its owner's address. | Released v0.1.0 | repo · page |
| OnlyKrida | Athlete discovery for India: tested, coach-verified results and opportunities for players the scouting pipeline doesn't reach. | Waitlist | onlykrida.com |
| Supercortex | A local-first quant research desk that counts every backtest so the Deflated Sharpe Ratio stays honest, with an Indian crypto-tax cost model and a falsification engine whose job is to kill ideas. Backtests only. | Research prototype | repo |

- Protocol details that lose people money. ZIP 316 unified addresses, ZIP 320 TEX, consensus branch IDs, memo and destination-tag rules, refund timelocks.
