Provable

Zero-knowledge toolkit for private web apps

Overview

Provable provides a toolkit to build privacy-focused apps using zero-knowledge proofs on the Aleo blockchain. It includes Leo, a programming language that helps create formally verified zk apps, plus an SDK, an API to the Aleo network, and a Leo playground; in 2025 it acquired Leo Wallet to enable privacy-preserving transactions. The platform enables private-by-default web services where user data remains under the user’s control, using decentralized systems and zk cryptography to prove correctness without exposing sensitive information. It differentiates itself by pairing a dedicated privacy-oriented language with open tools to abstract low-level cryptography and by fostering a privacy-first Web3 development ecosystem.

Simplify's take

What believers are saying

  • Shield Wallet launched February 2026 with private stablecoins, bridging, and compliance integrations.
  • Shield Swap opened early access August 17, 2026; public launch is targeted for Q4 2026.
  • Provable reported TVL on Shield Swap at $1.84 million by November 13, 2026.

What critics are saying

  • Aleo’s narrow ecosystem limits liquidity; Shield Swap still depends on bridged external assets.
  • Leo Wallet’s roadmap freezes after November 2025 acquisition, risking user migration churn and fragmentation.
  • If Shield adoption stalls, Provable becomes an ecosystem lab with no standalone revenue engine.

What makes Provable unique

  • Provable owns Aleo’s core stack: Leo, Shield Wallet, SDK, and explorer infrastructure.
  • Shield Swap launched August 17, 2026 with programmable disclosure and encrypted compliance records.
  • Howard Wu’s cryptography pedigree anchors differentiated zero-knowledge execution from research to shipped products.

Provable launches Shield Swap, a confidential trading venue protecting trader identities while enabling compliance

Provable has opened early access to Shield Swap, a non-custodial trading venue designed to protect sensitive financial information whilst supporting compliance. The platform keeps participant-level data confidential, including wallet balances, portfolio composition and trading strategies, whilst maintaining publicly verifiable pool reserves, trade prices and fees. Shield Swap generates encrypted compliance records for every trade. Participants can share information with regulators or auditors using view keys and selective disclosure without exposing their entire financial history. The venue currently supports USDCx on Aleo, a dollar-denominated stablecoin backed 1:1 by USDC held in Circle xReserve, alongside assets such as Wrapped Bitcoin, Ethereum, Solana and Aleo. Early access began on 17 August 2026, with a public launch anticipated for Q4 2026.

Provable opens early access to Shield Swap, a confidential trading venue built for compliance. Advertorial Dmitriy Maiorov 18 August 2026, 06:22 UTC Updated 18 August 2026, 06:22 UTC Editorial Note Provable Inc. ("Provable"), the company behind Shield Wallet and Aleo, backed by established investors in financial technology and cryptography, today announced Shield Swap, a non-custodial trading venue designed to protect sensitive financial information while supporting compliance. Beginning today, institutions, businesses, and government entities can request early access at shield.fi. Confidential positions. Verifiable markets. Public blockchains expose information that professional trading firms ordinarily protect, including wallet balances, portfolio composition, transaction history, and trading strategies. Shield Swap is designed to keep that participant-level information confidential without obscuring the market itself. Pool reserves, trade prices, transaction sizes, and fees remain publicly verifiable. A participant's identity, balances, portfolio, and links between transactions remain shielded. Shield Swap's shared anonymity set strengthens as participation grows. Participants can access their own wallet-level information through owner-controlled view keys, including balances, portfolio composition, and unrealized profit and loss. Compliance without public exposure. Shield Swap produces an encrypted compliance record for every trade. Transfers of supported dollar-denominated stablecoins also generate transaction-specific records. Using view keys and selective disclosure, participants can share the information required by a regulator, auditor, or counterparty without exposing their entire financial history. This allows firms to demonstrate compliance while preserving the confidentiality of unrelated positions and transactions. The venue currently supports the world's first confidential and compliant stablecoin, USDCx on Aleo, a dollar-denominated stablecoin backed 1:1 by USDC held in Circle xReserve. In addition, the venue also supports assets such as Wrapped Bitcoin, Ethereum, Solana, and Aleo in its beta period. "Serious trading firms do not publish their books or broadcast their positions. Yet public blockchains have forced market participants to do just that," said Howard Wu, founder and CEO of Provable. "Shield Swap takes a different approach: market activity remains verifiable, while identities, portfolios, and strategies remain confidential. Compliance is built into the system rather than added after the fact." Shield Swap opens to early access on Monday, August 17, 2026, with a public launch anticipated for Q4 2026. About Shield Swap. Shield Swap is a non-custodial institutional trading venue for confidential, compliant digital asset markets. It keeps market activity publicly auditable while protecting participant identities, portfolios, and trading strategies. Selective disclosure gives participants control over who can access their financial information and for what purpose. About provable. Provable builds confidential and compliant infrastructure for financial markets. Its products include Shield Wallet and Shield Swap, and Provable is also the team behind Aleo, a Layer-1 blockchain powered by zero-knowledge cryptography. Provable develops the cryptographic systems, protocol infrastructure, and software that enable confidential transactions with programmable disclosure. More information is available at provable.com.
