Chainlink CCIP EVM Contracts: Architecture from Source Code

EVM chains are isolated by design. A contract on Arbitrum has no native way to call a contract on Base, and sending USDC from Ethereum Mainnet to Polygon is not a built-in operation. Cross-chain bridges filled that gap for years, but the category has seen repeated security incidents that highlight how wide the attack surface is.

Circle CCTP V2 EVM Contracts: A Source-Code Walkthrough

Moving USDC across blockchains comes down to two designs. Lock-and-mint freezes the original token on the source chain and issues a wrapped version elsewhere, concentrating a large TVL target inside a single smart contract. Burn-and-mint does the opposite: the source chain burns the original, and a trusted authority mints an equal amount on the destination. No lockbox, no wrapped variant.

ERC-8004 Agent Reputation: On-Chain Registration and Lookup

A prior post on this blog covered the ERC-8004/8126/8196 trust stack: three Ethereum registries that handle agent identity, reputation, and validation. If you want the conceptual overview first, start there. This post is about something narrower: how feedback actually gets written to the Reputation Registry, how to read it back, and what services are available today to browse and index that data.

Agentic Payments in June 2026: x402, UCP, and MPP Implementation Progress

Agentic payments in June 2026 moved from “can an agent pay” toward “who authorized the payment, how is it verified, and how is it traced.” The major open protocols (x402, UCP, MPP/pay.sh, and ACP) each had meaningful implementation changes. All figures and commit details below come from GitHub API, PyPI, and npm registry checks.

AI x Blockchain in 2026: Bittensor, DePIN, and Agent Finance

“AI plus blockchain” spent most of the early 2020s as a marketing phrase. By mid-2026, it has organized into four distinct layers, each with its own competitive dynamics. Which projects have staying power, and what are the actual evaluation criteria at this point?

Figure: From HELOC Lender to Blockchain-Native Capital Markets

Two companies go by the name Figure. One is Figure AI, the humanoid robotics company. The other is Figure Technology Solutions, which is what this post is about. They are unrelated.

Lighter: A ZK-SNARK Orderbook DEX on Ethereum

Decentralized exchanges come in two main forms. AMMs (Automated Market Makers) like Uniswap set prices algorithmically from pool ratios and work as permissionless swap venues. Orderbook DEXes match individual buy and sell orders by price and time priority, the same way centralized exchanges like Binance or Coinbase operate. Orderbooks enable limit orders, tighter spreads with active market-making, and more precise price discovery. AMMs do not.

The AI Agent Trust Stack: ERC-8004, ERC-8126, and ERC-8196

When an AI agent acts on behalf of a user (spending funds, calling contracts, accessing paid APIs), the obvious question is: how do you know this agent is safe? The Ethereum community has three standards that address different layers of that question. They don’t solve the whole problem, but they’re building toward a coherent stack.

Secret Voting Architecture with FHE, SP1, and Groth16

On-chain secret voting creates three tensions at once. Votes must stay hidden while still being tallied. Off-chain computation cannot be trusted without proof, yet results need to land on-chain. And the EVM cannot run heavy cryptographic operations natively, but it still needs to verify them. FHE (Fully Homomorphic Encryption), SP1 zkVM, and Groth16 each take on one of these.
