- Wallet
- Your key to the ledger — an account only you control, secured by your device's fingerprint or face. Your pieces and money are recorded on Base; the wallet is what proves they are yours.
- Passkey
- A sign-in that uses your fingerprint, face or device lock instead of a password. Nothing to remember, and nothing a scammer can talk out of you.
- Base
- The public ledger Bifrost records certificates on. Maintained by thousands of computers, readable by anyone, owned by no one.
- USDC
- A digital dollar. One USDC is designed to always be worth one US dollar, backed by real dollars and short-term government bonds held by a regulated issuer.
- Gas
- The small processing fee a ledger charges to record a transaction. On Bifrost, checkout covers it for you — you will never be asked for it separately.
- On-chain
- Recorded on the public ledger itself, where it cannot be quietly edited or deleted — as opposed to sitting in one company's private database.
- Certificate
- The permanent on-chain record of one physical coin: which coin, which edition, who owns it, and every hand it has passed through.
- Mint
- The act of writing a coin's certificate onto the ledger for the first time. Also, by happy coincidence, the kind of house that strikes the physical coin.
- Drop
- A scheduled first sale of a new set, at a fixed price, direct from the issuing house. Once a drop sells out, the pieces trade on the open market.
- Edition
- One coin's number within its limited run. Edition 17 of 200 is a specific, individual coin — not a share of one.
- Floor price
- The lowest price any piece of a design is currently listed for. A quick, honest anchor for what getting in costs today.
- Provenance
- The unbroken ownership history of a coin. On Bifrost it is public, permanent, and only ever grows.
- Royalty
- The creator royalty — 2.5% by default, set per series and embedded in the series' smart contract — paid automatically to the house that created the series on every resale. It is the reason creators stay engaged with their coins long after the first sellout.
- Vault fee
- Bifrost's 2.5%, taken on every trade — primary drops and resales alike — for secure vault custody, insurance and the permanent record. Buyers never pay it; on a resale it comes out of the seller's side, who nets 95%.
- Custody
- Where the physical coin is right now: in the vault, in transit, or in its owner's hands. The certificate records which, at all times.
- Vault
- The insured, audited facility where coins physically live. Vaulted coins can change owners in seconds, because the metal never has to move.
- Redemption
- Asking for your vaulted coin to be shipped to you. It arrives insured and sealed; the certificate simply notes that it is now in hand.
- Settlement
- What happens after you sign: Bifrost relays your signed payment and runs every leg of the trade for you — seller proceeds, creator royalty, vault fee, certificate transfer — re-verifying each step on-chain as it goes.
- Self-custody
- You hold your own certificates and money in your own wallet — they never sit in a Bifrost balance between trades. The vault stores metal; you keep everything else.
- Transaction hash
- The unique fingerprint of one event on the ledger — a receipt anyone can look up, forever, without asking permission.
