Why this, why here, why now

A Central Asian sovereign, held in an offshore SPV, split into Senior and Junior claims on Base.

Central Asia sovereign tranche

Uzbekistan USD Eurobonds — London / AIX listed, English law — held in an offshore SPV and split into Senior and Junior claims on Base.

No Central Asian sovereign on-chain yet

Not found on rwa.xyz or major tokenization platforms as of Sept 2026, so far as we can verify.

Uzbekistan's sandbox is live

Since Jan 2026: stablecoin payments, tokenized securities, and USD/EUR bonds for local issuers.

Engine · USDC

Tranche waterfall on standard vaults

Every settlement runs one rule, in code. Senior is paid up to its fixed rate first; Junior takes what remains. Everyone settles at the same confirmed price, USDC-native on Base.

Senior tranche

Priority ▲

Paid first, up to its fixed rate. The protected claim on the Eurobonds.

Junior tranche

First loss ▼

The levered claim: takes first loss, then everything that remains once Senior is whole — gains or losses.

Compliance · CB Verify

Coinbase Verifications, not an admin list

Eligibility is checked on the share token itself, reading Coinbase Verifications attestations on Base. A verified wallet joins automatically; a revoked one is blocked instantly.

Permissioning

Eligibility on the token

The gate reads Coinbase Verifications on Base. Verified wallets join automatically; revoked ones are blocked instantly.

Standards

Permissioned securities

Transfer restrictions and country attestations enforce jurisdiction rules — on standards counterparties already accept.

Data layer

x402 gated data layer

NAV, settlement and risk data serve only through a metered API. Holding the institution token is the credential; each query spends it.

How the tranche works

One core — engine, compliance and data — that any institution can point at any asset without building a fund stack.

Deposit on the Base spoke, route over CCCP V2, settle on the Bifrost hub — every step recorded in the data layer.

01

Deposit on the Base spoke

A Coinbase-verified wallet deposits USDC. The Senior and Junior vaults and the risk manager check subordination before intake.

02

Route over CCCP V2

Relayers with a two-thirds quorum carry deposit and redeem requests to the Bifrost hub, and NAV, settlement and supply back to Base.

03

Settle on the Bifrost hub

The valuation contract runs the waterfall at one confirmed, quorum-signed NAV. Every product, request and permission is recorded in the data layer.

Questions about the submission

What is this Base Batches submission?+

Omni-Fi wraps Uzbekistan's USD Eurobonds (London / AIX listed, English law) in an offshore SPV and splits them into a protected Senior claim and a levered Junior claim on Base. As far as we can verify, no Central Asian sovereign is on-chain yet — not on rwa.xyz or major tokenization platforms.

How can Senior carry a fixed rate?+

Tranching redistributes the return. Junior is paid last and absorbs first loss, so Senior can be paid up to its fixed rate first. Junior takes whatever remains, gains or losses. Every investor settles at the same confirmed price.

Who can invest?+

Eligibility is checked on the share token itself, reading Coinbase Verifications attestations on Base — not an admin allowlist. A verified wallet joins automatically, a revoked one is blocked instantly, and country attestations enforce jurisdiction rules.

What is the x402 data layer?+

NAV, settlement and risk data serve only through an x402 metered API. Access is paid in a token issued to verified institutions, and each query spends it — holding the token is the credential, so the payment gate is the access control.

What are the risks?+

Junior absorbs loss before Senior, so the levered claim can lose value. Deployments run on test networks and nothing here is an offer or financial advice.
