Bridge BTC into Bitcoin’s DeFi Layer and put it to work on LayerBankWhat is Rootstock (and RBTC)?Rootstock is Bitcoin’s DeFi layer: a smart-contract chain secured by Bitcoin (merge-mined) with a 1:1 BTC-pegged asset called RBTC (used for gas and DeFi). In short: BTC in, RBTC out—so you can swap, lend, borrow, and loop with Bitcoin collateral. The canonical two-way peg is PowPeg; it converts BTC↔RBTC under Bitcoin-level security.Three ways to get RBTCOption A — Arbitrum → (swap) → Rootstock ✅ Often cheapestOn Arbitrum, swap WBTC → RBTC using Oku (Uniswap v3 UI).Oku pool: RBTC/WBTCTokens:WBTC (Arbitrum): 0x2f2a2543B76A4166549F7aAB2e75Bef0aefC5B0fRBTC (Arbitrum OFT): 0x441Fcb23dFe8289cf572126FEDCf450974ADc891Bridge RBTC → Rootstock via Stargate (LayerZero).Stargate bridge: Arbitrum→Rootstock, RBTCYou’ll receive RBTC on Rootstock at your configured wallet address. Keep a small amount of RBTC for gas.Why this route? You do one efficient swap on Arbitrum (deep liquidity, tight spread), then bridge RBTC directly, reducing extra swaps/fees on Rootstock.Option B — EVM → Rootstock → (swap on Rootstock)Bridge USDT0 or WETH to Rootstock via Stargate.Stargate bridgeTokens (Rootstock):USDT0: 0x779Ded0c9e1022225f8E0630b35a9b54bE713736WETH: 0x2F6F07CDcf3588944Bf4C42aC74ff24bF56e7590On Rootstock, swap USDT0/WETH → RBTC using Oku, Sushi, or WoodSwap.DEX links:https://www.sushi.com/rootstock/swap https://woodswap.org/home https://oku.trade/app/rootstock/tradeWhen to use: If you already hold USDT0/WETH on another EVM chain and want a simple bridge → one swap on Rootstock.Option C — BTC Mainnet → Rootstock (PowPeg)PowPeg (canonical 1:1 peg): Strict, on-chain BTC↔RBTC with longer confirmations.When to use: You hold native BTC and prefer to stay within the BTC peg system.What You Can Do on LayerBank (Once You Have RBTC)Supply RBTC to earn base yield + incentives.Borrow USDT0, RBTC, or WETH and loop (deposit → borrow → buy/mint → repeat) to amplify APY.Track yields and incentive streams via Merkl/LayerBank dashboards.LayerBank appMerklTips, Fees & SafetyGas: Keep a small RBTC buffer for transactions on Rootstock.Slippage: Check price impact on large swaps (both on Arbitrum and Rootstock).Bridge fees & timing: Stargate fees vary; compare Option A vs B briefly before executing.Security: Always confirm token contracts and bridge URLs. Start with a small test.
