So, you and your agent can win up to $100K this weekend: On Friday, we announced Synthesis, an agentic hackathon built in collaboration with the Ethereum ecosystem. Agents build onchain with the help of humans. A group of agents evaluates them. The best projects win real prizes. More on our bounty, here. You have until March 23 to submit.
Btw, if you’re looking to go deeper on agentic design, OKX recently launched Agent States, a new series exploring the future of agentic money. This week’s session with Mark dove into trading, and what agents actually need to get started. And if you’re after a breakdown of Uniswap AI skills, Nick and Cody have you covered.
Come build in Cannes: We’ll be at EthGlobal in a few weeks, and we’re giving away 30 free tickets to Pragma. If you’re interested, fill out this form. First come, first served. See you in the south of France.
Uniswap is now live on Tempo: Uniswap v2, v3, and v4 are now live on Tempo, the new payments-first chain incubated by Stripe and Paradigm. Tempo has a stablecoin DEX built into the chain for stable-to-stable pairs. Everything else settles through Uniswap. An aggregator hook wraps Tempo’s stablecoin DEX as v4 pools, so both liquidity sources are available in every swap. This marks the first live deployment of aggregator hooks, a v4 primitive that can turn any onchain liquidity source into a Uniswap pool. Aggregator hooks will go live on more chains, and with support for more liquidity sources, soon.
We also shipped a pay-with-any-token skill for Tempo’s new Machine Payments Protocol (MPP) so agents can pay for any 402 challenge with whatever tokens they already hold. A free API key is all you need to get started. To use the skill: npx skills add uniswap/uniswap-ai --skill pay-with-any-token
New hook templates just dropped: Space and Time launched new hook templates that let developers use cryptographically verified historical onchain data to open the door to things like loyalty pricing, dynamic fees, MEV defense, and LP reputation systems. Three templates are live now, so builders can customize the SQL and skip the rest of the plumbing.
MetaMask integrates the Uniswap API: MetaMask has integrated the Uniswap API as one of its swap providers. When MetaMask users swap, they get direct access to Uniswap’s deep liquidity, competitive pricing, and reliable quotes. The API is free to integrate: no subscription fees or per-call charges, even as you scale. If you’re building a wallet, aggregator, or trading product, sign up and start generating your keys.
D’CENT adds Uniswap API support: Now you can swap tokens across Ethereum and major L2 networks directly within the D’CENT wallet, with access to onchain liquidity and self-custody secured by hardware. D’CENT’s biometric hardware wallet uses fingerprint authentication to help protect your assets, while its mobile app provides a simple way to access swaps and other DeFi features.
Unichain integrates the Chainlink data standard: This week, Unichain integrated the Chainlink data standard and joined the Chainlink Scale program. Devs can now access Chainlink Data Feeds to build secure DeFi applications on Unichain. The integration also introduces Smart Value Recapture (SVR), which routes non-toxic MEV back to the protocols where it originates, complementing Unichain’s verifiable priority ordering. More infra, less friction for builders and protocols deploying onchain.
What would you build with 38M+ day one users? WorldBuild is back for its third edition, backing ambitious founders building new apps on World. Participating teams can unlock up to $200K in grants funding, fully funded trips to in-person sessions in Seoul and SF, and 50+ mentor hours from global founders. Submissions are now open, and you should apply.
Quick hits:
Permissionless capital at work: 400K+ new LP positions since the start of the year.
The expressive protocol: 25K v4 hooks initialized since v4 launched.
Actually based: Base just crossed $300B in all-time Uniswap Protocol volume.
