, this article is purely for on-chain security/bridge technology enthusiasts. At 3 AM, I used Anvil to fork the latest block of the Plasma mainnet (fork-block-number latest) and deployed the pBTC bridge contract, completing the BTC locking → pBTC minting → DeFi collateral → redemption process. @plasma.
Test results:
- The actual gas redemption measurement is 15% lower than the documentation (I added gas profiler for comparison)
- Redemption delay of 38 minutes (Watcher monitoring + multi-sign confirmation + MPC signature, configuration adjustable)
- No double flowers, no ineffective releases, ZK-SNARK proof ensures UTXO uniqueness
- Liquidation mechanism: Ethena delta-neutral hedging (USDe hedging) + automatic rebalancing, $XPL staking provides an additional buffer pool
Core mechanism breakdown:
1. BTC locking: Mainnet uses OP_CHECKSIGVERIFY + OP_CHECKLOCKTIMEVERIFY scripts, locking to a multi-signature address at the 8/15 threshold. Watcher nodes (decentralized) monitor and trigger cross-chain messages after confirmation.
2. pBTC minting: Plasma side threshold signature verification lock, ZK-SNARK generates proof (prevents double spending), 1:1 minting of pBTC.
3. DeFi usage: pBTC enters Aave V4 fork, Euler, Morpho and other pools, with a maximum collateralization ratio of 75%.
4. Redemption: burn pBTC → MPC signature → release BTC mainnet multi-signature.
Code quality is impressive: a mix of Rust and Zig, unsafe memory optimizations for the pBTC module + rayon parallelism, high comment density, each line of gas optimization is explained. Certik + PeckShield dual audits, zero high risk, all medium risks fixed. BTC pegged assets account for over 35% in TVL (depth 1.8B+), stablecoin supply over 2.1B+, over 100 DeFi partners (Aave, Ethena, Euler, Morpho, Pendle, etc.), on-chain trading volume is genuinely increasing.
$XPL value is clearest here: the $XPL consumption for complex cross-chain/liquidation operations directly burns + repurchases + staking rewards; the more the network is used, the stronger the deflation. $XPL is currently oscillating between 0.12-0.13, unlocking and digesting, staking/burning has been initiated, and the value anchor is shifting to 'bridge usage tax'. The Binance CreatorPad reward pool of 3,500,000 XPL is still ongoing; I post technical articles to earn points, like the hardcore sequel of Alpha points.
If you are also a tech enthusiast, would you dare to clone the Plasma monorepo and fork the mainnet to test pBTC redemption?
Local bridge redemption hardcore challenge
1. git clone Plasma monorepo + Anvil/Hardhat fork mainnet
2. Deploy the pBTC bridge contract, complete the lock → mint → redeem
3. Record gas consumption, latency, any risks/optimization points
4. Screenshot Anvil logs/contract interactions + write your findings/suggestions
5. Comment section @Plasma security team + post results
I help the top 5 most rigorous/insightful/issue-finding @officials seek Easter eggs (pinned + bug bounty or co-audit possible). The comment section becomes a 'on-chain security lab'—who measures the deepest, who discovers the most critical issues, whose suggestions resonate most with the team? Show it off. Infrastructure security is tested line by line in code.
