Upgradeable DeFi contracts tie emergency exits to rewrite power. My proposal is for Ethereum DeFi builders to separate them.

The power to rescue funds from a DeFi contract and the power to rewrite that contract are two different things, but today a single admin key often holds both.Many DeFi smart contracts are upgradeable, meaning an admin key can swap out the code governing deposits, loans, trades, and withdrawals while the contract address stays the same. Teams keep upgrade keys because software has bugs and a critical flaw needs a fast fix, but a key that can patch a bug can also rewrite withdrawal rules or take funds from everyone who has already deposited, which is a massive centralization risk.Here is my proposal:Instead of depositing directly into a protocol, users could route their funds through a small, immutable safety contract they choose themselves. The user keeps full control of normal deposits and withdrawals, while a separate backup key has the capability to do only one thing, which is to trigger an emergency exit that sends the funds to a safe address the user set in advance. If the backup key holder detects a vulnerability while protocol withdrawals still work, it can pull the funds out immediately without waiting for the user to come online. If the backup key is compromised, the attacker can only force an early exit back to the user's own address, which costs fees and interrupts a strategy, but cannot steal the funds.A safety contract can only use the exits a protocol already offers, so it cannot recover funds that a bug has already trapped or that an attacker has already stolen. Where a protocol only returns a token representing the deposit rather than the underlying assets, the emergency exit gives the user direct control of that token, but leaves the money exposed to the broken contract until the user redeems it. An extension of this idea would be to allow the safety contract to automatically redeem the token for the underlying asset, before effecting a withdrawal of the underlying asset.Once emergency exits sit with users, the main argument for upgrade keys in the protocol itself gets much weaker, so core DeFi contracts should be immutable by default. Upgrading an immutable protocol means deploying a new version and letting users move their funds over themselves, so nobody can impose new code on existing deposits. Voluntary migration splits liquidity across versions for a while (like when Uniswap released v3, and a significant share of the liquidity was still living on v2), but it asks users for their consent again instead of assuming it through an in-place upgrade.If this model were implemented, I predict it would make immutable DeFi the norm, with the rescue function living at the user's edge and the shared protocol remaining credibly neutral. via /r/ethtrader https://ift.tt/dbHKgam

Who's catching KENDU's dips? On-chain look at 19–27 Oct

Still building kenduconviction.com, and it's growing into something way bigger than I expected (more on that soon). Meanwhile I ran its data on one question: when KENDU is sold, who's buying?19–27 Oct, on Ethereum, Base and Solana. Times are UTC. Arbitrage is left out.The short version$2.03 per million at the start, $1.79 on Sunday night, $1.99 on Tuesday evening. About 2% down, with a lot of KENDU changing hands underneath.Who sold• A swing trader sold 4.0B on Sunday at 21:53 and bought 1.59B back seven minutes later. Over the nine days he bought about as much as he sold, so he's left out of the totals.• A top-30 wallet, in since October 2024, sold its whole bag: about 4.07B, Saturday to Monday.• Smaller exits: a February 2026 wallet trimmed 672M, two 2024 wallets sold out (270M), a May 2025 holder trimmed 124M, and two short stays left (311M).Who bought• A top-10 wallet bought 467M on Tuesday. It has bought every month for 27 months.• Five wallets that got their first KENDU this month bought 2.29B, including 773M on Solana that briefly pushed that pool to $2.21.• Long-time holders kept adding: a 29-month buying streak, an 11-month streak that has never sold, and two wallets in since 2024 that have never sold.• Selling outside arbitrage on Tuesday: under 6M.Better or weaker hands?Better.• Sold: 6.01B. Three-quarters of it (4.50B) came from exits and short stays. Long-time holders sold about 7% of the 6.01B.• Caught: holders and newcomers bought 4.35B, about 72% of what was sold. Active traders took 0.68B.• Still in the pools: 0.98B, mostly from last week. Since Monday, more has come out of the pools than gone in.A new wallet is a new address, not necessarily a new person.What the chain can't tell us: who these wallets belong to, why they bought, or where the price goes next. Solana before 26 Oct 13:30 could only be read as volume.PS: several buyers got "address poisoning" transfers right after moving their coins, from look-alike addresses with the same start and end as the real one. Never copy an address from your transaction history.Look up any wallet: https://ift.tt/D2SMtme sale: https://ift.tt/VTkf4Yz buy-back: https://ift.tt/Lvl3MF6 top-30 wallet's biggest sale: https://ift.tt/Hb7TyqB: Blockscout, Solana RPC, GeckoTerminal, kenduconviction.com wallet cards.🦊 via /r/KenduInu_Ecosystem https://ift.tt/9VsXvWw

How to choose wallet provider: Privy vs Turnkey vs Web3Auth

Hi everyone, I'm planning to build a wallet infra on my own instead of using a provider like Privy, Turnkey and Web3auth. Do you all think is doable? To what extent can the provider help me? Thank you in advances! Any suggestions will be helpful.A bit of context:Use case: embedded wallets for app users and possibly supports Scale: 1k - 10k daily active usersChains: Ethereum + EVM L2s, Solana, Robinhood, Tron etc (mainstream chains)Team: 5 backend SDE with 3 people working on cybersecurityWhat I’m trying to figure out:Is building in-house realistic for a team like ours? What are the hardest parts (key management, signing, security, compliance)?What do providers actually handle that would be painful to build ourselves?Is a hybrid approach common, like a provider for key management/signing with everything else built in-house?If you’ve gone either way, I’d really like to hear how it worked out and what you’d do differently.Thanks in advance! via /r/solanadev https://ift.tt/xTfC3Fl
