A marketplace for real-world shipping assets.

Bunkr connects two sides of a broken market. Shipping companies unlock working capital by tokenizing verified freight receivables.
Investors can earn 2–9% yield from real shipping transactions. Not synthetic yield.

Here’s what each side gets.

For shipping companies

  • Instant working capital

    Tokenize a verified freight receivable and draw capital the moment the raise fills — while the freight is still en route. No bank paperwork, no waiting 90 days.

  • One verification, reused

    KYB happens once. Every later invoice rides the same on-chain identity record — no re-onboarding per financing.

  • Priced per offering

    Working capital priced per receivable, not per relationship. No covenants, no months of bank approval. Interest escrowed up front.

For investors

  • 2–9% yield from real shipping

    Interest is set per offering and escrowed up front at token creation — funded before you buy, not promised after. Real-world shipping transactions, not synthetic yield.

  • SEP-57 compliant assets

    Every token is a permissioned, identity-gated asset backed 1:1 by a verified freight receivable from a working shipping lane. Transfers revert to unverified wallets.

  • Short cycles, $USDC settlement

    Invoice terms run 30–90 days. Principal plus interest pays out at claim, in $USDC. No lock-up beyond the invoice maturity.

The lifecycle is on-chain. All five stages.

Verification to repayment runs through the factory contract on Stellar — a decentralized escrow that holds USDC end-to-end. No intermediaries, no counterparty risk. Every stage below is a deployed contract call.

  1. 1.0

    Verify

    KYB for shippers, KYC for investors — recorded on-chain before any token exists.

    identity_verifier::​set_identity
  2. 2.0

    Tokenize

    An approved invoice becomes its own permissioned token; interest and fees escrow up front.

    factory::​create_rwa_token
  3. 3.0

    Fund

    Investors buy shares 1:1 with $USDC; when the raise fills, the shipowner draws the capital.

    factory::​buy_shares → collect_fund
  4. 4.0

    Settle

    The customer pays; principal returns to the pool and the offering flips to Settled.

    factory::​settle_debt
  5. 5.0

    Claim

    Tokens burn; investors collect principal plus interest. Redeemed, not resold.

Investors don’t chase cargo customers. The originator does.

Investors generally can’t tell whether an invoice is genuine, whether the customer is reliable, or how to run a collection. A professional originator can — so Bunkr routes every financing through one. The originator verifies invoices, monitors payment, fronts the recovery process, and earns a fee for the work.

Investors underwrite a verified asset, not a stranger’s paperwork.

The chain can’t make a customer pay.

A smart contract automates what happens after money arrives. When money doesn’t arrive, recovery is a process — staged, priced, and written into the terms before anyone funds.

  1. L1

    Friendly reminder

    Most late invoices aren’t fraud — they’re forgotten. A nudge two days past due clears a surprising share.

  2. L2

    Formal notice

    A lawyer’s letter with a 14-day demand. The signal: this debt is administered, not hoped for.

  3. L3

    Negotiation

    Damaged cargo, a missing invoice, stuck approvals — legitimate reasons exist. Three instalments beats zero.

  4. L4

    Collection agency

    Professional collectors work the debt for a percentage of what they recover.

  5. L5

    Legal action

    Court order, months to years. Last resort, priced accordingly.

Bars are indicative: each level costs more than the one before, so you escalate only when the level below fails.

The asset behind the token — freight, en route.

SEP-57 compliant. Compliance lives in the asset.

A Bunkr receivable is a permissioned, identity-gated token. Send it to an unverified wallet and the transfer reverts. Mint and burn require admin permits. The marketplace enforces its own rules — no off-chain enforcement layer.

Identity-gated transfers
Both sides of every transfer are checked against the identity registry.
Signed permits
Mint and burn require an ed25519 admin permit — nonce-protected, deadline-bound.
Role gating
KYB for shippers raising capital, KYC for investors buying shares.
Balance caps
The compliance contract enforces a per-token maximum balance on every hop.

    The complete business lifecycle on a permissioned custom token — verification, tokenization, funding, settlement, claims. Live on testnet.

  2. Phase 2 · Pilot

    Controls

    Freeze and clawback, refunds on failed raises, default states, the reserve pool, and the on-chain reputation ledger.

  3. Phase 3 · Production

    Full SEP-57

    The complete ERC-3643-style suite: trusted-issuer registry, claim topics, modular compliance — identity enforced by the token contract itself.

Not yet on-chain, and labelled as such: freeze, clawback, refunds on failed raises, default states. The roadmap is the point — the token upgrades to full SEP-57 without changing the business around it.

Every settlement writes a record.

Traditional trade finance forgets. Bunkr’s ledger doesn’t — each financing that settles, or fails to, accrues to the borrower’s on-chain history. Pricing follows reputation: reliable shippers raise faster and at lower cost.
