Tempo

The blockchain for payments at scale.

Tempo is a blockchain designed specifically for stablecoin payments. Its architecture focuses on high throughput, low cost, and features that financial institutions, payment service providers, and fintech platforms expect from modern payment infrastructure.

You can get started today by integrating with the Tempo testnet, building on Tempo, running a Tempo node, reading the Tempo protocol specs or by building with Tempo SDKs.

What makes Tempo different

• TIP‑20 token standard (enshrined ERC‑20 extensions)

  • Predictable payment throughput via dedicated payment lanes reserved for TIP‑20 transfers (eliminates noisy‑neighbor contention).
  • Native reconciliation with on‑transfer memos and commitment patterns (hash/locator) for off‑chain PII and large data.
  • Built‑in compliance through TIP‑403 Policy Registry: single policy shared across multiple tokens, updated once and enforced everywhere.

• Low, predictable fees in stablecoins

  • Users pay gas directly in USD-stablecoins at launch; the Fee AMM automatically converts to the validator’s preferred stablecoin.
  • TIP‑20 transfers target sub‑millidollar costs (-.tar.gzplus.sha256(archive checksum) and.asc` (GPG signature), and is also covered by Sigstore-signed SLSA build provenance.

The tempoup installer performs these checks automatically on every install. To verify manually, pick one of the two paths below — both prove the archive came from the tagged commit, signed by tempoxyz.

Path A — offline / no GitHub auth required (checksum + GPG):

TAG=v1.6.0
ARCHIVE=tempo-${TAG}-x86_64-unknown-linux-gnu.tar.gz

gh release download "$TAG" --repo tempoxyz/tempo \
  -p "$ARCHIVE" -p "$ARCHIVE.sha256" -p "$ARCHIVE.asc"

sha256sum -c "$ARCHIVE.sha256"

# Public key + fingerprint:
# https://docs.tempo.xyz/guide/node/installation#verifying-releases
gpg --verify "$ARCHIVE.asc" "$ARCHIVE"

Path B — Sigstore (requires gh installed and authenticated):

TAG=v1.6.0
ARCHIVE=tempo-${TAG}-x86_64-unknown-linux-gnu.tar.gz

gh release download "$TAG" --repo tempoxyz/tempo -p "$ARCHIVE"
gh attestation verify "$ARCHIVE" --repo tempoxyz/tempo \
  --predicate-type https://slsa.dev/provenance/v1
