BASE RAIL / B20

LOWER-COST RAILS.SAME PRECISE METER.

Metr's B20 work focuses on making small onchain settlement units more economical while keeping token configuration and payout paths explicit.

LOW-COST SETTLEMENT / 01

Cheaper movement matters at small scale.

When billing units are tiny and frequent, transfer overhead affects the product. The engine isolates token-specific configuration so a rail is enabled only after it is verified.

CAPABILITY MAP04 SYSTEM PRIMITIVES
01SAFETY
CFG

Configuration gates

Keep each token rail disabled until its contract and decimal assumptions are verified.

02FUNDS
DEP

Verified deposits

Credit access only after the expected network and token transfer can be confirmed.

03SETTLE
PAY

Payout path

Use the same session receipt to connect measured usage to the final movement of value.

04ENGINE
TEST

Fail-closed tests

Exercise registration, payout, and rejection paths before a rail is enabled.

WORKFLOW / 02

THE SYSTEM
IN MOTION.

Each stage has a visible input, an explicit state, and a result the next stage can verify.

  1. 01
    Register

    Add the network, token contract, decimals, and enabled state to configuration.

    enabled = false
  2. 02
    Verify

    Test deposit recognition and failure handling against the selected rail.

    tests = pass
  3. 03
    Enable

    Open the rail only for products explicitly configured to use it.

    enabled = true
  4. 04
    Observe

    Measure actual settlement behavior and costs instead of publishing estimates as facts.

    cost = observed

VISIBLE EVIDENCE / 03

MAKE THE STATE
READABLE.

Product activity should leave a trace a developer, operator, or customer can understand. The showcase uses realistic sample data where a live feed is not connected.

FOLLOW THE
SYSTEM.

01
ONE TOKEN. MEASURED WORK.

METR is the existing community token on Base. The product direction is simple: connect token demand to measurable software and agent activity.

02
TURN ACCESS INTO A MEASURABLE PRODUCT.

Set a rate, choose a billing unit, and collect from funded balances without forcing every customer into a monthly plan.

03
REAL VALUE NEEDS CLEAR BOUNDARIES.

See how authorization, funded balances, session states, receipts, and fail-closed behavior shape the Metr security model.
