Changelog

Only changes that affect integrators are listed. R-xx ids are the project's internal decision numbers.

30 Sep 2026

• SwapRouter (R-49) 0x397E…31E4: chains multiple hops (ClpPools, OracleAMM, ETHw vault) into one transaction, e.g. BTCw → ETHw. Quote API + SDK 1.2.0 add the router route; contracts.json adds SwapRouter.
• ETHw as a bridge destination (R-48): ETHw ⇄ USDw oracle-priced vault 0xFd6d…9D54 (OracleTokenAMM, ± 0.3%, max 300 ETHw per trade); the Bridge page lets you receive/send ETHw the same way as BTCw. contracts.json adds OracleTokenAMM_ETHw. Quote API and SDK 1.1.0 add the amm-eth route (also used by the Swap tab).
• SDK importable directly from btcw.tech: /swap/sdk/btcw-swap.js and /developers/contracts.json are served with CORS (Access-Control-Allow-Origin: *, 5-minute cache) — pages on other domains can import / fetch them in the browser.
• 100 US-stock price-tracker tokens (R-47): NVDAw, AAPLw, MSFTw… — 100 new pools, 201 pools / 202 assets in total. PriceHub prices them from 5 stock-market quote sources; OracleRebalancer is the minter and the keeper that holds pool prices, as for the crypto tokens. /api/v2/pools adds the class field; the Dashboard and Swap page have Crypto · US Stock · Stablecoin tabs.
• Multi-page docs replace the single-file page. Old /developers/#… links redirect to the new pages; search is available (/ key).
• Swap quote API for third-party wallets (R-46): /api/v2/swap/assets, /api/v2/swap/quote and SDK /swap/sdk/btcw-swap.js 1.0.0 — any pair among 102 assets can be swapped, with a prebuilt transaction returned.

29 Sep 2026

• OracleRebalancer (R-45) 0x6c811003…2e69 becomes the minter of the 100 price-tracker tokens and pulls pool prices back to the oracle (mint cap 300 BTCw/day). Its volume is counted in of_which_treasury; /api/v2/stats adds treasury_addresses.
• Bridge open to all wallets (R-44): allowlistEnabled = false on all 4 routers. The Bridge page adds an option to receive/send BTCw directly. /developers/ and /developers/contracts.json published.

28 Sep 2026

• Hyperlane bridge Arbitrum ⇄ 482120 (R-39, R-40): two routes, USDC and USD₮0 ⇄ USDw, initially allowlisted wallets only.
• 100 price-tracker tokens + 101 CLP pools (R-35), Dashboard and the /api/v2/stats|pools|history|swaps API (R-36), Swap page (R-41).
• BETA label (R-38) on every page: live mainnet, features still being finished.
• On-chain names, symbols, errors and events follow the English EVM convention (R-34).

25 Sep 2026

• USDw 0x3b5B…e727 and OracleAMM 0xd953…F51E go live (R-32) — all contract parameters are adjustable after deployment (R-31).
