An open ERC standard and full automation layer for recurring payments on Ethereum and EVM chains — pull payments, full state management, cross-chain — without intermediaries.
No spam. Early access updates only.
Two previous attempts to standardize onchain subscriptions have failed. Cadence is built to fix that — permanently.
Required offchain relayers to execute payments, introducing centralization, trust assumptions, and a single point of failure. No test cases were ever written. The proposal stagnated and was never finalized.
Built exclusively for NFT-based memberships. No pull payment mechanism, no state management (pause, grace period, retry), and no support for commercial SaaS-style subscriptions. A partial solution to a much bigger problem.
| Feature | ERC-1337 | ERC-5643 | Cadence |
|---|---|---|---|
| Native pull payments | ✗ Requires relay | ✗ None | ✓ Fully onchain |
| State management | ✗ None | △ Basic | ✓ Active / Paused / Cancelled / Expired / PastDue |
| ETH + ERC-20 support | △ Partial | ✗ None | ✓ Currency-agnostic |
| Cross-chain payments | ✗ None | ✗ None | ✓ ERC-7683 intents |
| Grace period & dunning | ✗ None | ✗ None | ✓ Configurable per merchant |
| Automation layer | ✗ None | ✗ None | ✓ Keeper + Gelato fallback |

Cadence is not just a smart contract. It's a complete stack — an open standard, an automation service, and a developer toolkit.
An open Solidity interface for onchain subscriptions. Deployable by anyone, auditable by everyone. Becomes the shared standard the ecosystem builds on — like ERC-20 for tokens.
The keeper layer that actually executes payments. Indexer, scheduler, executor, dunning manager, webhooks — all managed so merchants don't have to run their own infrastructure.
TypeScript SDK, React hooks, CLI, subgraph, Foundry snippets. Drop-in integration for any EVM project. Built to match the DX expectations of modern developer tooling.
Every layer of Cadence is designed to be composable, permissionless, and production-grade.
The core interface defines everything a subscription needs: who pays, how much, how often, and what happens when payment fails. Fully compatible with ERC-20, ERC-165, and ERC-7683 for cross-chain intents.
A production-grade service that handles execution so merchants never have to. From indexing onchain events to dunning management — everything runs automatically.
From npm to CLI, Cadence is designed to integrate in minutes, not days. The same experience developers expect from Stripe or Alchemy — but fully onchain.
@cadenceprotocol/sdk — TypeScript SDK with viem/wagmi wrappers and React hooks@cadenceprotocol/cli — deploy, manage, and inspect subscriptions from the terminalCadence is currency-agnostic and chain-agnostic. If it recurs, it runs on Cadence.
Monthly API access, RPC nodes, developer tools — billed in USDT or ETH, collected automatically, no invoices.
Recurring dues for governance rights, token-gated access, or community benefits. Auto-cancel on non-payment.
Newsletters, research, media — subscription-based monetization for creators without a payment processor.
Agents paying agents — recurring micropayments between autonomous systems, fully onchain and permissionless.
Box subscriptions, physical goods, recurring orders — managed natively in crypto for merchants on Shopify or custom storefronts.
Streaming subscriptions for indexers, oracles, bridges — pay-as-you-subscribe for onchain infrastructure providers.
Five converging forces make 2026 the exact moment to standardize onchain subscriptions.
Stripe relaunched crypto payments in 2024 and is actively building onchain payment rails. When Stripe integrates a subscription standard, it will move the entire merchant ecosystem with it.
Coinbase's Base chain has crossed meaningful TVL and daily active user thresholds. A subscription standard deployed on Base has immediate access to a distribution network of millions of Coinbase users.
Autonomous AI agents are increasingly executing tasks that require recurring micropayments — to each other and to services. Onchain subscriptions are the native payment primitive for the agentic economy.
USDT and USDC liquidity is now deep and reliable across all major EVM chains. Merchants can accept stablecoin subscriptions without meaningful exchange rate or liquidity risk for the first time.
The two prior attempts (ERC-1337, ERC-5643) have both failed or been abandoned. The standard-setting race is still open. The first well-implemented, well-adopted ERC wins by default.
Major financial institutions are actively exploring onchain settlement. A subscription standard today becomes the infrastructure they adopt tomorrow — the same way ERC-20 became the default for tokenized assets.
Cadence captures value at the protocol level on every collected payment — while generating compounding stablecoin volume for the tokens it runs on.
We're looking for strategic partners who understand the infrastructure opportunity — stablecoin issuers, chain ecosystems, and fintech investors who want early positioning in the onchain subscription standard.
