 - [One Signature, Every Chain: EIP-8130's Protocol-Level Account Abstraction](https://tryethernal.com/blog/eip-8130-protocol-level-account-abstraction): EIP-8130 proposes native AA with chainId=0 config sync. No bundlers, no per-chain key rotations. Here's how the mechanism actually works.
 - [The Frame Wallet: What EIP-8141 Means for Every EOA](https://tryethernal.com/blog/eip-8141-frame-transactions-eoa-abstraction): EIP-8141 gives unmodified EOAs gas abstraction via default code and a new frame execution model. No bundlers, no migration, no new wallet.
 - [The Address That Existed Before the Contract: ERC-8185 and ERC-8186](https://tryethernal.com/blog/erc-8185-8186-counterfactual-identity): ERC-8185 and ERC-8186 create deterministic on-chain addresses for GitHub repos, domains, and npm packages, before their owners have ever touched Ethereum.
+- [The Missing Subscription Primitive: How ERC-8191 Standardizes On-Chain Recurring Payments](https://tryethernal.com/blog/erc-8191-onchain-recurring-payments): ERC-1337 failed. ERC-5643 is too narrow. ERC-8191 learns from both: a pull-based subscription lifecycle with soft-fail collection and a keeper model.
 - [The Mandate Pattern: Bounded Execution Authority for ERC-4626 Vaults](https://tryethernal.com/blog/erc-8192-mandated-vault-execution): ERC-8192 fills the gap ERC-4626 left open: how to delegate vault execution to AI agents and solvers without giving up risk control.
 - [The State Growth Tax: Inside Ethereum's Proposal to Charge You for Dormant State](https://tryethernal.com/blog/ethereum-tiered-state-write-pricing): New EIP draft prices SSTORE by age: dormant state costs more to write. How period tracking works and what this means for DeFi protocols with idle positions.
 - [Ethernal Is Going Open Source!](https://tryethernal.com/blog/ethernal-is-going-open-source): Ethernal's code is now publicly available on GitHub. The hosted version now has free and paid tiers.
