Lido now has $1B in pending withdrawals.
Lido estimates ~15 days for withdrawals.
Current Lido validator exits cover just 58% — and take ~8 days to process.
Without a lot more validator exits, the real wait will be much longer.
@OriginProtocol's Lido ARM is helping users exit while generating strong yield for LPs.

I love seeing the merkle proofs of OETH's validator balances and deposits in action on Ethereum mainnet

Uninstall the Pocket Universe browser extension.
The "small" fee is 80 basis points on swaps :-(

It's been a good week for the Origin ARMs. They tend to do well when crypto prices are falling.

Origin’s ARM helps support LST stability during market volatility.
➡️ $stETH ARM: 7.6% APY
➡️ $eETH ARM: 7.4% APY
When markets get choppy, the ARM captures price dislocations through arbitrage, generating elevated ETH yield while reinforcing LST pegs across secondary markets.

sol2uml now shows what functions are called on contract dependencies.
The latest release also contains bug fixes and performance improvements.
@claudeai did all the code changes and testing

The $OETH staking upgrade has passed governance and is now deployed.
This marks the start of OETH’s transition to Merkle Proof–based validation: a major step toward fully trustless Ethereum staking.
Validator migration begins this month 🧵 (1/2)

This makes me happy as a smart contract developer.
Thanks @NethermindSec, @sigp_io and @OpenZeppelin for their security audits.
The new staking strategy that uses merkle proofs of beacon chain data is now in the governance pipes.

Hardhat 3 is now in beta, and ready for production use!
Hardhat 3 is a complete overhaul. We introduced Solidity tests, rewrote the performance critical components in Rust, added multichain support across the board, implemented OP Stack simulation, revamped the build system, modernized our TS CLI and plugin system, and a lot more.

Over the past 6 Weeks, I’ve been building bera-reth, a Reth SDK execution-client with enshrined proof of liquidity without forking Reth.
10 PRs contributed to Reth/Revm to support our use case.
Now live on the Berachain Bepolia Testnet. 🧵

Testing merkle proofs of beacon chain data to verify OETH validator balances is coming along nicely

I'm learning how to construct merkle proofs of beacon chain data.
The generalized index is powerful, allowing any beacon chain data to be proved against the beacon chain root.

sol2uml now supports @etherscan's V2 API
The one API key can now be used across all Etherscan's supported testnet and mainnet blockchains.

tx2uml has been upgraded to support @etherscan's V2 API.
This means the same API key can be used for any chain supported by Etherscan.

Ethereum partial withdrawals delivered with the Pectra upgrade have been disappointing. 4.5 days to process 4 requests.
Can anyone explain why these are so slow?

Was just looking at Origin Protocol's stats in our Grafana.
Over the last two years we've grown our TVL 4.7x, and we've 6x'd our yield sent to users.

The Lido ARM hit a 48.0% APY today📈
Seizing the opportunity with low $stETH prices the ARM recovered 73% of liquidity (2,512 $WETH) at a massive 17-20 basis point discount!
Now hitting an impressive 11.3% 30-day APY.
Deposit $ETH into the ARM on our dApp to live the experience🔹
