Yours Wallet Rebuilt from Scratch for BRC100 and AI Agents

One of BSV's most widely used browser extension wallets is getting a complete rewrite. Developers David Case and Dan Wagner have spent months rebuilding Yours Wallet from the ground up to fully implement the BRC100 standard — the wallet-to-application interface that allows wallets and dApps to communicate seamlessly across the BSV ecosystem.

The architectural change is significant. The new version splits the codebase into a React/Framer Motion frontend and a background service worker for wallet logic, replacing the old monolithic structure. Every wallet function — sending BSV, transferring Ordinals, signing messages — is wrapped in a self-describing "action" with a JSON schema. Crucially, all those actions can be automatically converted into MCP-compatible tool definitions via the @1sat/actions package, meaning an AI agent can discover and call wallet operations using the same Model Context Protocol that Anthropic and major AI platforms have adopted as the standard for agent-tool communication.

Storage is handled locally by default, with optional metered cloud backup at 1 GB free then satoshis-per-gigabyte — enforced by BRC-29 payment protocol so anyone can operate a storage provider. The team is dog-fooding the new build internally and seeking community testers before an official launch announcement. The Chrome Web Store still serves the February 2026 legacy build.

Why it matters: BRC100 and MCP together could make every BRC100-compatible wallet on BSV directly operable by AI agents without bespoke integration work. Yours Wallet is the first BSV wallet to explicitly build for this combination, and if the pattern catches on, it accelerates the path toward a fully agent-native BSV ecosystem where wallets function as tool endpoints as naturally as APIs do today.

US Regulators Open TradFi Doors for Blockchain: SEC Approves Clearing House, CFTC Greenlights Bitcoin Perpetuals

Two US regulatory decisions this week shifted the legal landscape for blockchain in traditional finance. On May 28, the SEC granted full registration to Paxos Securities Settlement Company (PSSC) as the first blockchain-native registered clearing agency and central securities depository in the US — a milestone seven years in the making. The day after, the CFTC approved KalshiEX to offer the "BTCPERP Contract," the first CFTC-registered perpetual Bitcoin futures contract in the country.

The Paxos approval is the more structurally significant of the two. A blockchain-native clearing agency means same-day settlement and reduced counterparty risk are now legally viable within US capital markets infrastructure — not as an experimental pilot but as a registered, regulated entity. It operates alongside legacy systems like DTCC for now, but the regulatory template exists. CFTC Chairman Michael Selig noted the Bitcoin futures approval was designed to reverse the offshore drift of crypto derivatives innovation and align with the administration's goal of cementing the US as a crypto-capital.

For BSV specifically, neither approval names the chain directly. But the pattern matters: the regulatory window that Chronicle-era BSV has been building toward — stable protocol, courts-of-law dispute resolution, enterprise-grade throughput — is the same window these approvals are opening. A registered blockchain clearing house needs a settlement layer with predictable fees and provable immutability. BSV's architecture targets exactly that specification.

Why it matters: When US financial regulators move from "guidance" to "registration," adoption timelines compress. The Paxos clearinghouse creates a compliance template that enterprise blockchain vendors will immediately begin mapping their offerings to. BSV's locked protocol and Teranode's scaling roadmap position it well for that template — but the window is now competitive, not just theoretical.

Data covers blocks 951,870–951,996 (sampled at 10 representative heights from ~140 blocks mined between 00:13–23:49 UTC on 3 June 2026).

• Blocks mined on June 3 UTC: ~140 (heights 951,870 – 952,009)
• Highest-volume block: 951,884 — 152,316 txns, 28.2 MB (taal.com, 02:27 UTC)
• Largest block by size: 951,954 — 150,188 txns, 42.3 MB (taal.com, 14:19 UTC)
• Third peak: 951,968 — 105,026 txns, 19.6 MB (CUVVE, 18:06 UTC)
• Active miners: taal.com, CUVVE, Mining-Dutch, GorillaPool.com, qdlnk, Bitofsin

June 3 produced three distinct high-volume peaks — blocks 951,884 (152K txns), 951,954 (150K txns, largest at 42.3 MB), and 951,968 (105K txns) — showing sustained capacity utilisation across the UTC day rather than a single isolated burst.

Wallets, Regulations, and the Infrastructure Layer BSV Is Building

Two seemingly unrelated stories share a common direction: the infrastructure layer for the next wave of blockchain adoption is being assembled. In San Francisco, developers are rebuilding wallets so AI agents can use them without human intermediaries. In Washington, regulators are creating the first legal frameworks for blockchain settlement within traditional finance. Both moves matter for BSV's thesis.

The Yours Wallet rebuild is a small but precise signal. BRC100 standardisation and MCP tool compatibility are the developer-infrastructure preconditions for an agent-native economy. When a wallet becomes a set of MCP-callable actions, the barrier between "an AI agent deciding to pay for something" and "an AI agent actually paying for something" collapses to a single protocol call. BSV's sub-cent fees and Teranode-era throughput are the economic substrate that makes the per-transaction economics viable. The wallet rebuild is the UX layer of that stack arriving.

The regulatory story is slower but potentially larger. The Paxos clearing house creates a compliance template. Any enterprise wanting to build blockchain-based settlement within US capital markets now has a registered, regulated reference architecture to work from. The seven-year engagement with the SEC was the price of entry; the payoff is a legal framework that other builders can reference without repeating the same regulatory journey.

The risk for BSV remains the same: building the right infrastructure without the distribution to fill it. taal.com and CUVVE pushed three blocks above 100,000 transactions on June 3 — proof the capacity exists. Yours Wallet and BRC100 provide the developer interface. The Paxos clearinghouse opens the institutional channel. The missing variable is adoption momentum: enough anchor applications generating enough real transaction demand to make BSV the default settlement assumption rather than the considered alternative.

Risks to Watch

• Paxos template competition — the SEC clearinghouse approval will accelerate rival blockchain settlement products; BSV must be positioned when enterprises evaluate settlement layer options
• Yours Wallet launch readiness — the rebuild is in internal testing with no announced timeline; competing BSV wallets that ship BRC100 first gain the agent-integration head start
• Teranode mainnet gap — three 100K+ txn blocks on June 3 show demand building against current node software; Teranode mainnet delivery timing is the critical next milestone
• Regulatory scope creep — CFTC/SEC approvals are narrow; further clarification on blockchain-native securities settlement and stablecoin rails could shift timelines significantly
