 +===== What it is =====
 +
 +A web wallet for Tari layer 1 that also givent derived from the same 24-word recoveryphrase. Keys are generated and every transaction is built and signed locally in WebAssembly; the page talks only to the public base node query service and the O
 +
 +The headline feature is **Burn to Ootle**: ule meant running ''minotari_console_wallet''plus the Ootle wallet daemon, copying proof files between them, and waiting. In this wallet it is one form:
 +
 +  - Pick an amount and burn. The burn transaction is signed in the browser and broadcast.
 +  - The wallet watches for the burn to be minerkle proof from the base node itself.
 +  - Once the Ootle validators accept the L1 block (about 100 blocks deep on Esmeralda, under an hour), the wallet
 +    claims it into your Ootle account as private
 +
 +You can also burn to any other Ootle accountproof for them, and claim a burn madeelsewhere (for example a ''minotari_console_wallet'' proof file) from the Ootle side.
 +
 +===== What it adds over Tari Universe (desktop) =====
 +
 +  - Runs in any browser, with nothing to download and no chain to sync (scanning runs in parallel web workers agathe public query service).
 +  - MainNet and Esmeralda testnet, chosen with a toggle when you create or restore a wallet. - Ootle built in: public and private sends, ering private funds, the testnet faucet, anda catalogue of Ootle apps. - Burn to Ootle with automatic claiming, as
 +  - A dApp connector (''window.tari'') with the same provider API as the Sapient extension, so an Ootle dApp works either wallet.
 +  - Also: PIN lock and auto-lock, sub-addresses, opt-in sender reveal, sign-now-broadcast-later, and developer to
 +
 +===== How it’s built =====
 +
 +The burn flow needed new pieces at three layers, all mirroring the reference wallets exactly:
 +
 +  - **L1 burn builder** (''tari_l1_wasm'', vendored in the repo): builds a burn the way the console wallet’s ''burn_does. The on-chain claim key is the stealth e Ootle account key never appears on chain;the encrypted value is keyed to ''DH(P, r)'', and ''r\` derives from the commitment mask, so a burn’s proof can be regenerated from the seed.
 +  - **Ootle wasm** (''burnClaimStealthSecret'', ''validateBurnClaimOwnershipProof''): derives the claim secret ''s = H(p·R) + p'' that seals the claim, and checks the ownedator will, before anything is submitted.
 +  - **Ootle SDK** (''OotleAccount.claimBurn''): mints the burn with ''ClaimBurn'' and spends it into a stealth output owned by the account, sealed with ''s''. The fee is claimed value, and a stealth-revealed fee is never refunded, so the fee is measured with a dry run (metered cost plus the engine’s estimate allowance) rather than padded.
 +
 +===== Verification =====
 +
 +Tested end to end on Esmeralda with real tra
 +
 +  - A 10 tXTM burn, mined in L1 block **914,01986744 tTARI** (claim transaction ''4df34e29632a2db78f4f1cb0a9766fe5d7197a88d1b1b734d03ba42deab251a4''). Fee: 13,256 µT, the 13,244 metered plus the 12 µT allowance, so nothing was overpaid.
 +  - A cross-implementation fixture: a burn built by the new L1 builder is verified by Ootle’s own ownership-proof check and decryption, in the Ootle wasm test suite
 +  - The L1 burn passes the base node’s own transaction consistency validator in a native test.
 +  - Two bugs found and fixed along the way, bo only by ''s'' was rejected with “no mainsigner” because the TS transaction builder leaves the seal signer unauthorised by default; and balances hid stealth
 +    funds for accounts not yet on chain, which ied burn lands.
