Introducing LastcoinVision

August 3, 2026

LastcoinVision (LCV) is a Cosmos SDK Layer-1 built for a specific pair of audiences: governments that need auditable infrastructure for voting, tax, land registry, and identity, and the developers who build on top of it. This post is a straightforward account of what's actually running today — not a pitch.

The chain

LCV is a standard Cosmos SDK application (lcvd) on CometBFT consensus, with IBC enabled. Total supply is fixed at 10,000,000,000 LCV, allocated at genesis across ecosystem grants, foundation treasury, team and investor vesting accounts, a staking-rewards pool, and public and community allocations. There is no open-ended inflation — staking rewards are paid out of that fixed pool on a ten-year decaying emission curve. Transaction fees follow an EIP-1559-style dynamic base fee with a governance-tunable burn.

Government modules

Three custom modules exist specifically for government use cases:

• x/registry — a non-fungible asset registry for land and other titled assets, with full transfer history and jurisdiction-authority freeze powers.
• x/voting — eligibility-gated elections using a commit-reveal scheme, so anyone can recompute a tally from public on-chain data. (More on what this does and doesn't guarantee in the next post.)
• x/taxrail — atomic split-payment transfers that route a jurisdiction's tax share to a transparent treasury in the same transaction as the transfer itself.

All three sit on top of x/identity, which anchors W3C-style DIDs and credential hashes — never the underlying personal data — so other modules can gate access on a verified account tier without the chain ever holding anything sensitive.

Smart contracts, for everything else

Governments aren't the only intended users. LCV also runs CosmWasm (governance-gated code upload, permissionless instantiate) and an Ethereum-JSON-RPC-compatible EVM with a native two-way bridge to the Cosmos-side balance. Reference contracts exist for both — escrow, invoice factoring, healthcare consent registries, procurement workflows — as a starting point for ERPs, commerce platforms, and other applications that don't need a custom module.

For developers

@lastcoinvision/sdk gives typed clients for every custom module plus Keplr and MetaMask wallet helpers, and npx create-lcv-app scaffolds a working dApp against a local devnet in one command. See the developers page to get started.

What's next

This is testnet/devnet software: no independent security audit has happened, and there's no production network. The roadmap tracks what's built, what's in progress, and what's still planned — including the documentation site, public testnet infrastructure, and the security review that has to happen before any of this is production-ready.
