Bringing the real world to BTC

Real-world assets (RWAs) are the hot topic in crypto right now. Gold, Treasuries, credit funds—all being tokenized and brought onchain. But while tokenization is new, the idea of a digitally scarce, real-world-backed asset is not.

In fact, the original RWA is Bitcoin itself.

Unlike any other digital asset, Bitcoin is rooted in physical reality. It is mined with electricity. It is scarce by design, mathematically capped at 21 million. It has survived 15 years of market cycles, attacks, forks, and experiments—emerging every time as the reserve asset institutions trust when they enter crypto.

That’s why public companies add BTC to their balance sheets, why sovereigns consider it part of their reserves, and why its $2T+ market cap eclipses all other digital assets combined. Bitcoin is already “digital gold,” and as trillions in traditional assets move onchain.

Simply put: Bitcoin stands apart as the strongest collateral and the most liquid settlement layer.

The challenge is that Bitcoin’s base layer was never designed to host complex financial products. Until recently, the only way to make BTC “productive” was to wrap it on other chains. That fractured liquidity, added custodial risk, and turned pristine Bitcoin into something institutions could no longer fully trust.

Arch makes Bitcoin productive in its native form: powering tokenized assets, yield strategies, and institutional-grade financial products without forcing them to bridge or wrap assets.

By extending Bitcoin with high-performance execution while preserving its settlement assurances, Arch allows developers to build everything from tokenized credit markets to stablecoin vaults directly against BTC itself.

This unlocks the end-game for bringing the real world to Bitcoin.

Tokenization is the next big wave. Institutions are eager to bring trillions in RWAs onchain, but they need security, liquidity depth, and settlement guarantees.

Today, they’re forced to deploy on ecosystems like Ethereum, Avalanche, or Solana, which fragment liquidity and rely on wrapped Bitcoin.

Institutions don’t want wrapped Bitcoin: They want the real thing, the asset that already dominates their portfolios, put to work in environments where custody is safe and liquidity is preserved.

Arch Network v0.5.10 is live!

We’ve shipped Arch Network v0.5.10, delivering a cleaner, faster, and more developer-friendly release. Highlights include a new sol_log_data syscall for structured program logging, repo cleanup that removed deprecated test_sdk and local_tester crates, and major CLI upgrades with base58 normalization fixes, more resilient mint creation flows, and refreshed docs. The SDK now includes a rent-exemption check helper, while CI/infra saw a full Associated Token Account workflow rewrite and improved crate metadata. Together, these changes streamline developer experience and improve observability, making it easier to build, debug, and scale Bitcoin-native applications.

On performance and reliability, the slimmer codebase translates into faster builds, while the new logging syscall enhances in-program diagnostics for troubleshooting. CLI edge cases around identifier handling and mint creation were fixed, and lingering test_sdk dependencies were removed from e2e tests. Importantly, there are no breaking changes at the protocol or API level—developers can continue building as usual while enjoying a smoother, more stable workflow. If you previously relied on test_sdk or local_tester, migrate to e2e-tests and runtime-tests equivalents and ensure scripts keep passing base58 identifiers to arch-cli.
