# 3.0 PRIME Sinks

Token-gated products, services, and experiences available for [PRIME](/echelon-prime-foundation/2.0-prime-token.md) are called Sinks.\
\
Several Sinks exist in [Parallel TCG](/echelon-prime-foundation/1.0-echelon-ecosystem/1.1-parallel-tcg.md). Some, like [Terminals](/echelon-prime-foundation/3.0-prime-sinks/3.1-live-sinks/terminals.md) and [Artigraph](/echelon-prime-foundation/3.0-prime-sinks/3.1-live-sinks/artigraph.md), are cosmetic. Others, like [Payload](/echelon-prime-foundation/3.0-prime-sinks/3.1-live-sinks/payload.md) and [Echoes](/echelon-prime-foundation/3.0-prime-sinks/3.1-live-sinks/echos.md), are critical for achieving scale.\
\
Sinks lock up circulating supply, refill the [Gameplay Pool](/echelon-prime-foundation/2.0-prime-token/2.1-gameplay.md), and reward stakeholders through [Sink Distributions](/echelon-prime-foundation/2.0-prime-token/2.2-sink-distributions.md).
