Portal to Bitcoin raises $25M and launches atomic OTC desk

Bitcoin-native interoperability protocol Portal to Bitcoin has raised $25 cardinal successful backing amid the motorboat of what it describes arsenic an atomic over-the-counter (OTC) trading desk.

According to a Thursday announcement shared with Cointelegraph, the institution raised $25 cardinal successful a circular led by integer plus lender JTSA Global. The fundraise follows erstwhile investments by Coinbase Ventures, OKX Ventures, Arrington Capital and others.

Alongside the caller funding, the institution rolled retired its Atomic OTC desk, promising “instant, trustless cross-chain colony of ample artifact trades.” The recently deployed work is reminiscent of crosschain atomic swaps offered by THORChain, Chainflip, and much Bitcoin-focused systems specified arsenic Liquality and Boltz.

What sets Portal to Bitcoin isolated is its absorption connected the Bitcoin (BTC)-anchored crosschain OTC marketplace for institutions and whales, on with its tech stack. “Portal provides the infrastructure to marque Bitcoin the colony furniture for planetary plus markets, without bridges, custodians, oregon wrapped assets,” Chandra Duggirala, laminitis and CEO of Portal, said.

Only autochthonal assets, without custody

Portal to Bitcoin leverages Hashed Timelock Contracts (HTLCs) crossed aggregate chains and Bitcoin Taproot contracts to swap autochthonal BTC for autochthonal assets connected integrated blockchains successful a non-custodial manner, with a beardown absorption connected reducing spot assumptions. HTLCs are designed to guarantee that either sides implicit the speech oregon some sides retrieve their archetypal assets.

It leverages BitScaler, a layer-3 resembling Lightning Network built connected apical of Bitcoin and utilizing Taproot and argumentation templates. It opens channels overmuch similar Lightning channels, introducing a hub-and-spoke operation wherever validator federation is the hub and liquidity providers are the spokes. Trades successful those channels are secured with HTLCs.

For the end-user, this means they bash not person to spot wrapped tokens with federations and alternatively woody lone with autochthonal assets connected their autochthonal chains. The strategy besides guarantees that if the relation halts mid-swap and HTLCs expire, funds tin beryllium reclaimed.

Duggirala told Cointelegraph that portion atomic swaps exist, THORChain and Chainflip are “based connected vaults taking custody of funds from some parties” that are controlled by validators. Unlike with Portal to Bitcoin, with specified setups, “a bulk of rogue validators tin perchance bargain each the vault-controlled funds.

Liquality and Boltz are person to Portal to Bitcoin successful their HTLC-based design, but they are mostly simple, one-swap-at-a-time tools, not a full liquidity furniture and DeFi stack connected apical of Bitcoin with pooled liquidity. This makes the task scope rather different.

The information assumptions

PortalOS has a Notary Chain built on the Ethereum Virtual Machine connected Cosmos (EVMOS), with validators called Portal Guardians. This web has 42 validator slots (now accrued to 150 according to Duggirala), with astatine slightest 21 targeted arsenic a minimum. Validator enactment is permissionless done a PBT staking auction. Still, Duggirala told Cointelegraph that currently, the validator acceptable is permissioned and permissioned auctions volition beryllium implemented later:

“We intentionally kept the archetypal validator acceptable to known entities and much concentrated for the elemental crushed of node bundle management.”

The documentation explains that specified a debased fig of validators was chosen intentionally and is not an issue, since they bash not power immoderate vaults oregon liquidity pools.

“Validators’ lone relation successful the DEX is to lucifer a purchaser and a seller, oregon 1 enactment with another. They bash not power the travel of funds,” Duggirala claimed.

Still, according to the documentation, validators power the Lightning hub and support the notary concatenation state, including pricing, liquidity excavation accounting, commercialized matching, and crosschain contracts for the protocol’s token. They are besides expected to assistance tally an automated marketplace shaper (AMM) erstwhile the strategy moves beyond its existent bid publication model.

That means that portion validators cannot straight prehend oregon frost idiosyncratic assets, they could inactive censor oregon hold swaps, misprice markets, disrupt the functioning of the AMM oregon halt the strategy wholly if they acted maliciously oregon became unavailable.
