[0.1.2] - 2026-03-09

browser.js CJS shim at package root for browserify compatibility (require('@ocash/sdk/browser') now resolves correctly without exports map support).
browser field in package.json: remaps dist/index.cjs → dist/browser.cjs for browserify, and stubs better-sqlite3, node:sqlite, node:fs/promises, node:path to prevent Node-only modules from entering browser bundles.

prepareWithdraw: send net recipient amount (requestedAmount) as burn_amount in relayer request, not the total UTXO deduction (burnAmount). Previously the contract received inp.amount = burnAmount and computed amountWithFee = burnAmount + protocolFee + relayerFee, which mismatched the circuit's public input, causing ZKP verification failure.
SqliteStore export moved from universal entry (@ocash/sdk) to Node-only entry (@ocash/sdk/node) to prevent Vite 7+ static analysis errors from import("sqlite") appearing in browser bundles.
