Oracles are services that supply off-chain data, such as asset prices, to on-chain smart contracts. The move addresses a longstanding bottleneck in how the EVM handles that data. Oracle contracts that push multiple price feeds in a single transaction accumulate compounding costs on the standard EVM because of how it processes 256-bit stack operations. According to RedStone's internal testing, switching to Stylus drops the base overhead from 35,000 gas to 23,000 gas per transaction, a reduction of 34.3%. The per-feed cost falls from 16,000 gas to 8,000 gas. In real-world scenarios using three data signers and eight price feeds, total gas consumption drops from roughly 297,000 gas to 218,000 gas, a saving of about 26%.

Arbitrum Stylus (officially launched in production in 2024) lets developers write smart contracts in Rust, C, and C++ that compile to WebAssembly bytecode. Those contracts run alongside Solidity contracts and share the same state, so they can call each other without bridging or wrapping. The performance gains come from WASM's more direct memory access and hardware-aligned data structures, which avoid the repeated stack overhead that makes EVM execution expensive for compute-heavy workloads like cryptographic verification.

"Stylus gives us the best of both worlds: native-speed WASM for compute and seamless interop with Solidity contracts," said Maja Cholewka, RedStone's marketing lead, in a statement published on the Arbitrum blog.

The migration is designed to be low-friction for protocols already using RedStone. Teams need only swap a contract address to point to the new Stylus deployment. Existing EVM adapters can stay live in parallel during any transition period, and RedStone says no re-audit is required because the cryptographic verification core, which handles ECDSA signature checks on the secp256k1 curve, remains unchanged. The company follows what it describes as an open-closed principle: a fixed, audited inner layer handling security, with new environment-specific modules added on top without touching that core.

RedStone currently secures more than $8.5 billion in total value across 70-plus blockchains and more than 180 protocols, according to the company's 2025 year-end report. Clients include Morpho, Compound, Pendle, and Venus. The network grew its client base by 63% year-over-year in 2025, though that figure comes from RedStone's own reporting and has not been independently audited. For context, the broader oracle sector secures an estimated $102.1 billion in total value as of October 2025, with Chainlink holding roughly 67 to 87 percent of that market. RedStone was the only major oracle provider to post positive growth in total value secured in the periods analyzed, rising from $6.3 billion in Q1 2025 to over $8.5 billion by year-end.

Regional Impact: Why This Matters Beyond the US and Europe

The gas savings carry outsized relevance for users in South Asia, Southeast Asia, and Sub-Saharan Africa. DeFi activity in those regions concentrates on high-frequency, low-value transactions: stablecoin transfers, small-scale lending, and remittance-adjacent products where protocol fees directly determine whether a transaction makes economic sense. India leads the 2026 Global Crypto Adoption Index. Nigeria accounts for 12.7% of all MetaMask users worldwide. Four Sub-Saharan African countries now rank in the global top 20 for crypto adoption, up from two in 2024. No direct RedStone partnerships with regional protocols in these markets have been announced; the regional impact described here is inferred from Arbitrum's geographic user distribution and the downstream effects of oracle cost improvements on protocols used across those markets.

Many of these users access DeFi largely through Arbitrum because its Layer 2 infrastructure keeps swap costs around $0.03, compared to several dollars on Ethereum mainnet. Arbitrum currently holds $16.63 billion in total value locked and processes roughly 46 million transactions per month, placing it among the most active Layer 2 networks. Efficiency improvements at the oracle layer flow downstream into the lending protocols and liquidity markets those users depend on, affecting liquidation thresholds, borrow rates, and price responsiveness.

For developers building on Arbitrum in markets like Lagos, Nairobi, Mumbai, or Karachi, the zero-re-audit migration path matters too. Smaller teams without large security budgets can adopt the more efficient oracle infrastructure without adding months of review cycles to their deployment timelines.

RedStone is already the primary oracle provider for Securitize, the tokenization platform backing BlackRock's BUIDL fund and Apollo's ACRED product. As tokenized real-world assets expand into South Asian and African markets, the oracle infrastructure pricing those assets becomes foundational to the entire financial stack. Cost efficiency at that layer has direct yield implications for end investors. Based on the trajectory of both the Stylus migration and the broader RWA market, RedStone appears positioned to serve that expanding use case at meaningfully lower overhead than its EVM-only baseline allowed.
