UX so smooth Paradigm thinks it's sponsored by coinbase 🫡. We’re a very small team & running the paymaster ourselves — on GitHub, GPLv3 and you can see it on-chain.
cb pays 20-40 cents per tx for your free daimo txs btw.

We applied for Optimism's RetroPGF for our P-256 verifier contract. Ours is the first (& so far only) audited secp256r1 verifier. It lets anyone use passkeys and device keys onchain. And like our app, it's all open source. Check it out below.

4/ How does it work under the hood? Intent addresses: a permissionless and non-custodial way to trigger any action from a single transfer. As always, our contracts and SDK are open source. The result is a flow that “just works”. Like Apple Pay: one popup → tap accept → done.

Oh, that's so cool to see the first audited P256 signature verifier: The secp256r1 elliptic curve, aka P256, is used by high-quality consumer enclaves including Yubikey, Apple's Secure Enclave, the Android Keystore, and WebAuthn.

3. Bundle compression. 4337 is the future. L2 is the future. However, 4337-on-L2 was too expensive. We found a nice, general way make it efficient—in our case, even cheaper than a plain EOA transfer!.

We built an SDK to fix this. Let your users pay from any coin, any chain, any wallet instantly. Try the live demo:
Bought my ticket for ETHDenver, spiritually the experience is the perfect epitome of how I feel about Ethereum atm. 1. Moongate doesn’t list base USDC as a payment option. 2. Tried to convert my base USDC into mainnet ETH, tx failed. 3. Then swapped all my base USDC back into.

We're using Shovel at Daimo to great effect. It's the cleanest, fastest way we've found to stream contract events into a database.
Thrilled to announce Shovel 1.0!. Since the beta release in Nov 2023 we found and fixed the major bugs, tuned the performance, and added a few small nice-to-haves. The 1.0 release is a nice stamp on a maturing code base and indicates its production readiness for Ethereum

This is a big opportunity. The Global Settlement Layer. Also big risk: walled gardens, regulatory capture, systemic exposure to centralized blacklists, . What can we learn from the past? How do we keep ETH on the best timeline? Here's how we see it.

6/n Looking forward, P256Verifier is also compatible with EIP-7212. With our idea of progressive precompiles, this enables smooth transition to a precompile performing P256 signature verification in future.

3/n P256 signatures are supported by a wide range of consumer devices, including modern phone hardware enclaves, Yubikey, Webauthn, passkeys etc. With P256 signatures, we can make much better Ethereum wallets: smoother onboarding, safer and easier self-custody, no seed phrases.

5/n With P256Verifier, we take the smart contract verifier approach. Today, P256Verifier is one of the most gas efficient and secure verifiers. Costs just 330k gas to verify a signature. No off-chain preprocessing necessary.

7/n Onboarding a crypto shop to Daimo, we got peppered with questions about keys and fees: "How do I pay fees without ETH?", "Where's my seed phrase?". These aren't just about Daimo, but about the future of the Real World Ethereum coming with account abstraction and rollups.

8/n Real World Ethereum will take sustained effort to percolate at the technical, the application and the social layer. With Daimo, we hope to package the liberatory potential of cryptography into a polished product anyone can use.

4/n Stablecoins are popular in places with weak or coercive banking systems. Two Chinese women told us about the underground scene there: people VPNing to Binance P2P, exchanging for USDT for freedom to travel internationally.

Why? The tech is ready + the "physics" of stables are irresistible. Even to tradfi: PayPal with PYUSD, Revolut, Visa. Robinhood just announced USDG, Stripe acquired Bridge. Soon, you'll open your banking app and send stables instead of wires. @liamihorne called it last year!.

6/n Ethereum has made tremendous progress, but that progress has long been hidden behind speculative and toy use cases. Between rollups, 4844 and contract wallets, Ethereum is about to offer a cheaper, better and more sound alternative.

5/n It's not that these users don't understand the security risks of Tron. There's just no viable alternatives, and Tron has deep-rooted network effects already. We got the same answers repeatedly:. "Most people in crypto I know use USDT / Tron"."Tron has low fees".

In short: ERC-1271 signatures should be unique even if two accounts share a signing key. This never happens in our app, but the contract is open source (GPL) and *other* apps could potentially use our contracts this way.

3/n Everyone Wants Dollars. The first exchange shop we visited had two logos out front: Bitcoin and Tether. But Bitcoin just served as a flag for crypto. No one used it in practice. The owner explained that most customers were foreigners exchanging USD cash to USDT on Tron.
