contract.dev

Introducing the Stagenet: A private testnet that: - replays real mainnet blocks - imports contracts via GitHub CI/CD - provides built-in analytics & devtools Start building now → contract.dev

100 reasons to keep posting about contract.dev. Giving away 100 days of credits. just comment what you’re building👇

@DeusOfConsensus Sorry for it we will get back to you soon on this

@contractdotdev please, what's wrong? Since yesterday...😔

@GAmitej This is what leadership looks like in defi. Hats off

The hardest week of my career. And also the week I saw what this industry is truly made of. We are contributing 2,000 ETH to DeFi United. Every rsETH holder will be made whole. That was always the only acceptable outcome for me personally. To everyone who showed up, thank you. DeFi United.

huge thanks to each and every one of you for the support would love to share what we've been cooking @contractdotdev still early but built something insane contract.dev isn't just another dev tool. it's a private EVM testnets that follow mainnet state, with built-in contract dashboards, a contract simulation framework, and tools for protocols like @Uniswap and @chainlink > stage contracts against real chain state. uniswap liquidity moves, chainlink feeds update, every protocol behaves exactly like production > track tvl, fees, balances in auto-generated dashboards. every contract you deploy gets its own workspace. no dune, no custom tooling > fire 10k txs at your contracts and see what breaks. simulations surface the bugs that only show up at scale yield drift, fee leaks, accounting errors > impersonate any wallet, override oracle prices to simulate crashes, spin up chainlink upkeeps in one click, push to github, auto-deploy to your stagenet sepolia is fake. anvil is frozen. forks drift the second you start them not a testnet. not a fork. a production-grade staging env for smart contracts would mean a lot if you check it out and drop feedback 🙏

@KiraPayOfficial Good luck with the rollout. If staging the v1.1 changes against real mainnet conditions ever gets useful, that's the lane we're in at contract.dev happy to chat anytime

📋 System Maintenance Notice KIRAPAY is currently offline for scheduled infrastructure maintenance. We're using this window to deploy stability improvements and prepare for the release of v1.1. Updates to follow. Thank you for your patience! 😈

@owenwg Polymarket on its own L1 is a serious move

@NeeleshW3 🤝

contract.dev isn't just another dev tool. it's a private, live copy of mainnet with contract dashboards, a simulation engine, and dev utilities built in. > stage contracts against real chain state. uniswap liquidity moves. chainlink feeds update. every protocol behaves exactly like production. > track TVL, fees, balances in auto-generated dashboards. every contract you deploy gets its own workspace. no dune. no custom tooling. > fire 10k txs at your contracts and see what breaks. simulations surface the bugs that only show up at scale yield drift, fee leaks, accounting errors. > impersonate any wallet. override oracle prices to simulate crashes. spin up chainlink upkeeps in one click. push to github, auto-deploy to your stagenet. sepolia is fake. anvil is frozen. forks drift the second you start them. not a testnet. not a fork. a production-grade staging env for smart contracts.

@CoinMarketCap Most of them were tokens looking for a game, not the other way around

LATEST: ⚡ Roughly 93% of Web3 gaming projects are now "effectively dead," according to Caladan, with token values down 95% from 2022 peaks and studio funding collapsing 93% by 2025.

@fhenix We see a privacy trust in these colours

Be honest…. what do you see?

@panditdhamdhere @Uniswap @chainlink Thanks for the kind words, means a lot. Let us know what you end up testing first, always curious what devs reach for

Just found another great Smart contract development tool - @contractdotdev Private EVM testnets that follow mainnet state, with built-in contract dashboards, a contract simulation framework, and tools for protocols like @Uniswap and @chainlink . Feels like a much better way to test contracts before mainnet. This significantly improves devX on chain. Smart contract maxis, if you’re building smart contracts, I encourage you to check out contract.dev

@Mantle_Official @KelpDAO @LayerZero_Core @aave Mantle stepping in with a loan facility is the kind of move that keeps the ecosystem intact

Following this week's rsETH incident involving @KelpDAO and @LayerZero_Core, a proposal has been put forward for Mantle to contribute a loan facility to @aave's coordinated relief effort. The loan would form part of a wider coordinated framework, structured to minimize disruption across the broader ecosystem and contribute to a measured path forward for users affected. DeFi United, as one. Full details below: forum.mantle.xyz/t/discussion-m…

How you doing good hooking? I built a dashboard for analysing and simulating @Uniswap V4 pools and hooks on a private testnet. How does your hook behave under sustained load? Learn more here: docs.contract.dev/defi/uniswap/v4

@Param_eth Rough month on paper, but every cycle like this forces the space to level up

Worst month for DeFi: - Drift hacked - rsETH exploit - Aave liquidity crisis - USDT frozen on Tron - Arbitrum is centralised - Multiple bridges drained - Lazarus group become more rich - Several protocols paused operations

ENSv2 is gonna create a lot of new integration surface. Wanted to share something we're building at contract.dev. We give teams private testnets that follow real mainnet state, so you can put contracts in production conditions before shipping. Feels like the kind of launch where that matters

ENSv2 is coming. A new foundation for names, built for integrations and subnames at scale. What will you build?

@okx watching builders ship through bear markets without flinching

what is your favorite thing about crypto?

@aave lido stepping up, this is the energy the space needs

Aave service providers have been leading the DeFi United effort to restore rsETH's backing since the April 18 incident. We believe ecosystem collaboration matters most in moments like this, and our priority is achieving the strongest possible available outcome for users. Multiple strong indicative commitments are now in place to join this effort toward restoring the backing of rsETH. This includes @LidoFinance, whose contributors have published a proposal today to their DAO to participate in the joint recovery effort. Lido is one of many partners who are stepping up. We will continue to announce further commitments as they are formalized.

@megaeth mega cooking something serious. tge week always shows who actually stress tested before shipping vs who's praying we live in that world at contract.dev
