Introducing a new home for @base builders and node operators. Helpful resources in one place: 1. Vibenet: an ephemeral devnet for beta testing features ahead of mainnet 2. Upgrades: track expected fork timelines and what will ship in each 3. Snapshots: reth v2 snapshots for faster node sync More coming soon

Base Chain information used to be scattered. Now it lives under one roof: Here's what's live on the new site. 🧵
@base v2 snapshots are live 🔵 - mainnet snapshots shrank from ~7TB → ~3.2TB due to a new chunked, better-compressed schema - sync times cut from ~5hr → ~2hr - pruned nodes land ~1TB if you run a base node, migrate before the mid-august MDBX hard limit deadline - credit: @wlaw_ @0xBoneyBoi 🙏

Building on @base and applying to @ycombinator - drop a line with what you’re building.
Native account abstraction is coming to @base and heres the break down! Let me know your questions below!
The Base Ecosystem Fund is funding founders building global finance onchain. A few areas we're excited about: • Tokenised assets and yield • Stablecoins for emerging markets • Onchain credit • Prediction markets • 24/7 FX and institutional markets • Agentic commerce And plenty we haven't imagined yet. Applications are open.

Base is for quality assets, serious teams. When we TGE’ed, it took us a month to set up audited contracts with multisig wallets. Now with launchpad, it takes a few mins to launch a venture-backed token. Single-sided Uniswap v4 launches with permanently locked liquidity, and tokens born admin-less: no mint, no pause, no seize. What B20 makes possible: - Tokens minted through the B20 precompile factory, fully set up in one tx - On-chain referrals with a referral fee share on every trade - Trade comments emitted on-chain — a native super-chat feed per token - Verifiable creator announcements, no token role required - Socials and metadata stored on-chain in the token itself - Team allocations minted at creation with on-chain staircase vesting - Vanity token addresses on the fixed 0xB20f prefix - Anti-snipe fair-launch window: fees decay from 99% to 1%. - Gasless approvals via native permit - Simple burns, no rebase games

Useful for devs working with onchain B20 data

The ActivationRegistry has officially been enabled marking B20s as live on @base mainnet Follow this guide to launch your B20:
Most tokens are smart contracts deployed on top of a chain. B20 tokens are native to Base - built directly into the protocol. The B20 Native Token Standard explained 🧵
Activating B20 in 15 minutes at 22:00 UTC Systems are 🟩 and we can't wait for the first B20s on Base 🟦
B20 activation will resume once Github services have recovered. Thanks for the patience
GitHub is experiencing degradation today. Out of an abundance of caution, we're discussing whether to delay B20 activation. Safety first.
Awesome to see @base community members shipping. @QuigleyNFT building @helixaxyz @rbthreek vibe coding a smart wallet trading app @0FJAKE podcasting with @rish_neynar @MrDegenWolf building the White Wolf community Links below. Not investment advice.

In anticipation of B20s on @base mainnet, I wanted to highlight a useful tool for devs: tl;dr: standard Foundry can't simulate Base precompiles; eg, the B20 Factory, Policy Registry. base-anvil is a fork of Foundry specifically for Base, so if you're already accustomed to this toolkit as an eth dev, you'll feel right at home.

Update on B20 activation. We appreciate your patience
With the recent network stability issues, we're pushing back the B20 Activation Registry mainnet enablement to ensure a smooth rollout. Sepolia and Vibenet remain on track. We'll share a revised date shortly.

Blocks are being produced normally, and we have verified widespread recovery in the ecosystem. Any remaining stuck Base nodes will recover upon restart and syncing. The team has found the root cause for this halt and we’ll share a full post mortem based on our learnings and fixes as a top priority.
