About Pontis

Secured by the Best

Pontis is an innovative bridge designed to seamlessly connect the Bitcoin ecosystem. The initial version focuses on integrating Runes and BTC as Pontis BTC on Stacks and EVM networks, along with bridging SIP10 <> ERC20 tokens. Pontis enhances the utility and accessibility of Bitcoin assets, creating new opportunities for decentralized finance and asset management.

Features

Bitcoin Asset Integration

Pontis bridges key assets across ecosystems, including:

• Runes

• BRC-20

• Ordinals

• BTC as Pontis BTC

• SIP10 <> ERC20 tokens

When sBTC becomes live on the Stacks mainnet:

• All Pontis BTC tokens will be converted to sBTC.

• The Pontis BTC bridge to Stacks will be decommissioned.

• On EVM networks, Pontis BTC will also transition to sBTC once the protocol goes live.

Roadmap

Current and Upcoming Goals

Feature	Status	Details
Support for Runes	Live	Full support for Runes bridging on Stacks and EVM.
Support for sBTC	In Progress	Pontis BTC migration to sBTC upon its deployment on Stacks mainnet.
Expand BRC20 support	Planned	Support for BRC20 token integration to unlock more Bitcoin asset capabilities.
Ordinals integration	Planned	Enable bridging of Bitcoin Ordinals across chains.
Additional L2s	Planned	Integration with non-EVM Bitcoin Layer 2s, Ethereum, Solana, and other ecosystems.

Security Model

Pontis employs a robust security architecture based on a multisignature setup across all connected networks. Each multisig participant functions as an independent node, responsible for validating and verifying every bridging transaction. Once a transaction is approved, the node signs it, ensuring a secure and decentralized process.

The nodes participating in the multisig setup are established and reputable projects from the Bitcoin and Stacks ecosystems. These projects include:

First Phase

• Asigna

• Bima

• BILLION•DOLLAR•CAT

• Bitflow

• DeSpread

• Ducat

• Hermetica

• Leather

• Liquidium

• OrdinalsBot

• Pontis

• Sats Ventures

• StackingDAO

• Xverse

• Zest

Second Phase

To be updated

Transition to Trustlessness

Pontis will transition from multisig to a Threshold Signature Scheme (TSS), enabling:

• Full decentralization of the signature process.

• Elimination of reliance on trusted participants.

• Enhanced security for bridging operations.
