1Shot API

The enterprise stack for programmable stablecoins—embed accounts, control permissions, and automate transactions without custodians, paymasters, or infra rent.

[1Shot API @1shotapi]

Creating the wallet is the easy part. The part that actually kills conversion: getting money out of the bank an onchain (without getting mogged by fees), paying gas, and finishing one real transaction.

@GetOnramper says up to half of fiat-to-crypto swaps still fail after KYC. That’s a lot of people who already said yes and then bounced.

1Shot teamed up with @circle to fix this.

$50 a week into BTC since January: +11.4%.
All at once on Jan 1: -7.1%.

That's the case for DCA. Try any amount, cadence, and date range for BTC, ETH, or PAXG with our new free calculator 👇

@arc Submissions close Nov 1. If you're wiring the wallet into an Arc Studio project and get stuck, reply here and we'll help.

Building for the @arc Microgrants? Your experiment has to move real USDC on Arc mainnet, so your users need a funded wallet.

Embed the 1Shot wallet: passkey sign-in, Circle Onramp built in, USDC on Arc. No API key, no onramp account of your own.

@BuildOnCircle One balance per asset across chains is a big deal for wallet UX. In the 1Shot passkey wallet we use CCTP so users never have to think about which chain their USDC is on, and EURC getting the same treatment opens that up for euro users. Do Nanopayments cover EURC at launch?

most are crypto-native and only a handful work on cards, stripe isn't the only one building the agent payment stack!

Our answers for the 1Shot wallet: keys stay on the user's device, raw key material never reaches your app or us, and there are no MAU or signature fees. Try it: https://t.co/HcaUUlIS3s

[1Shot API @1shotapi]

If an embedded wallet disappears with its provider, it was never really the user's wallet.

Three questions to ask before you pick one: who holds the key, who else sits in the signing path, and what growth will cost you.

[CoinOperated @CoinOperatedFi]

$0 to on-ramp. USDC lands on @arc. Your first BTC buy goes out on schedule. That's the whole setup. 🔁

Theming options and the embed quickstart: https://t.co/fnQplLjyr6

[1Shot API @1shotapi]

Your users should see your brand on the wallet, not ours.

The 1Shot wallet takes your product name and colors in one configure call. Passkey sign-in, gas paid in stablecoins and Circle Onramp all ship under your name. Free to embed, no API key.

[1Shot API @1shotapi]

@paularambles so are you supposed to eat the hamster if you get desperate?

[1Shot API @1shotapi]

1Shot embedded wallet is open source and implements signing logic in pure javascript with no third party dependencies.

[CZ 🔶 BNB @cz_binance]

Most projects should at least post a confirmation like this.

[Todd Chapman @TtheBC01]

We all gotta self-custody our money now, can't trust anything that you can't audit with your own AI.

Thats why we wrote the signing logic for @1shotapi embedded wallet in pure javascript with no dependencies.

Hopefully the browser vendors are a little safer that PHP

How session keys and ERC-7710/7715 delegations give an agent bounded, revocable authority instead of the keys: https://t.co/kYxYV5ITKq

[1Shot API @1shotapi]

Agents are getting wallets. The real question is how much they're allowed to spend.

With 1Shot delegated wallets, a user approves once and an agent gets a capped USDC budget. It can pass smaller slices to sub-agents, never bigger ones. The user keeps the wallet.

[1Shot API @1shotapi]

@samconnerone Ready. Clear final rules are what let regular apps offer USDC, not just crypto-native ones. That's the bet behind our free self-custodial passkey wallet, with Circle Onramp built in and gas payable in USDC.

[CoinOperated @CoinOperatedFi]

New: Buy the Dip 📉

Pick a coin, pick the drop, pick the window. Your wallet buys automatically when it happens, and the coins land in your own wallet.

No 3am chart watching. 🔁

[Todd Chapman @TtheBC01]

@CoinOperatedFi now has onchain enforced (EIP-7710) "Buy the dip" triggers.

So you can setup a plan that will buy bitcoin:native when prices say 3% in 6 hours. It uses your USDC on @arc network and the BTC gets sent to your personal wallet.

Works for $ETH and $PAXG too.

[1Shot API @1shotapi]

@corey__cooper The escrow one is a great end-to-end test. Pair the Studio-built contract with a passkey wallet on the front end and testers can fund and release escrow in USDC without ever holding a gas token. Fastest way to see the whole Arc flow from a user's seat.
