Soroban.ex is an open source library for Elixir to interact with the Soroban-RPC server, and facilitate the deployment and invocation of Soroban smart contracts.
Warning Please note that Soroban is still under development, so breaking changes may occur.
Available in Hex, add soroban
to your list of dependencies in mix.exs
:
def deps do
[
{:soroban, "~> 0.22.0"}
]
end
Soroban.ex is made up of three components:
Types
: Soroban types that can be utilized as function arguments when invoking a smart contract.RPC
: Interface to interact with the Soroban-RPC server.Contract
: Deploy and invoke Soroban smart contracts with ease. No need to worry about transaction building.
The Soroban.Types
context defines a comprehensive set of types that are crucial since they can be utilized as function arguments when invoking a smart contract.
The types provided by Soroban.ex aim to replicate the experience of working with types in smart contract development. They range from scalar types (such as Bool, Int32, etc.) to compound types (such as Map, Struct, Tuple, etc.).
Soroban.Types.Bool.new(true)
Soroban.Types.Bool.new(false)
These types include signed integers (Int32
, Int64
, Int128
, Int256
) and unsigned integers (UInt32
, UInt64
, UInt128
, UInt256
).
Soroban.Types.Int32.new(1)
Soroban.Types.Int64.new(1)
Soroban.Types.Int128.new(1)
Soroban.Types.Int256.new(1)
Soroban.Types.UInt32.new(1)
Soroban.Types.UInt64.new(1)
Soroban.Types.UInt128.new(1)
Soroban.Types.UInt256.new(1)
Soroban.Types.TimePoint.new(12_345)
Soroban.Types.Duration.new(12_345)
# From raw bytes
Soroban.Types.Bytes.new(<<1, 2, 3>>)
# From string
Soroban.Types.Bytes.new("Hello World!")
Soroban.Types.Symbol.new("symbol")
Soroban.Types.String.new("Hello World!")
# Account address
Soroban.Types.Address.new("GB6FIXFOEK46VBDAG5USXRKKDJYFOBQZDMAPOYY6MC4KMRTSPVUH3X2A")
# Contract address
Soroban.Types.Address.new("CCEMOFO5TE7FGOAJOA3RDHPC6RW3CFXRVIGOFQPFE4ZGOKA2QEA636SN")
Option
is a type that represents an optional value. It can hold any Soroban.Types
type.
# When the value is not present
Soroban.Types.Option.new()
# When the value is present
100
|> Soroban.Types.UInt32.new()
|> Soroban.Types.Option.new()
Vec
is a type that represents a vector of values. It can hold any Soroban.Types
type as long as all the values are of the same type.
values = [
Soroban.Types.Symbol.new("A"),
Soroban.Types.Symbol.new("B"),
Soroban.Types.Symbol.new("C")
]
Soroban.Types.Vec.new(values)
Tuple
is a type that represents a tuple of values. It can hold any Soroban.Types
type.
alias Soroban.Types.{Tuple, Symbol, Int32}
values = [Symbol.new("A"), Symbol.new("B"), Int32.new(1)]
Tuple.new(values)
Map
is a type that represents a map of key-value pairs. It can hold any Soroban.Types
type as key and value.
alias Soroban.Types.{Map, MapEntry, Symbol, UInt32, Bool}
key1 = Symbol.new("key1")
value1 = UInt32.new(100)
entry1 = MapEntry.new({key1, value1})
key2 = Symbol.new("key2")
value2 = Bool.new(true)
entry2 = MapEntry.new({key2, value2})
Map.new([entry1, entry2])
The Enum
type supports both unit and tuple variants. More info can be found here.
alias Soroban.Types.{Enum, UInt32}
# Unit variant
Enum.new("A")
# Tuple variant
Enum.new({"B", UInt32.new(100)})
Struct
is a type that represents a custom struct. It can hold any Soroban.Types
type.
alias Soroban.Types.{Struct, StructField, UInt32, Address}
key1 = "key1"
value1 = UInt32.new(100)
field1 = StructField.new({key1, value1})
key2 = "key2"
value2 = Address.new("GB6FIXFOEK46VBDAG5USXRKKDJYFOBQZDMAPOYY6MC4KMRTSPVUH3X2A")
field2 = StructField.new({key2, value2})
Struct.new([field1, field2])
Interaction with the Soroban-RPC server is done through the Soroban.RPC
module.
To interact with the Soroban-RPC server, it is required to create a Soroban-RPC server struct.
# with a custom URL
Soroban.RPC.Server.new("https://soroban-testnet.stellar.org")
Soroban.RPC.Server.testnet() # https://soroban-testnet.stellar.org
Soroban.RPC.Server.futurenet() # https://rpc-futurenet.stellar.org
Soroban.RPC.Server.local() # http://localhost:8000
Submit a trial contract invocation to get back return values, expected ledger footprint, and expected costs.

Submit a real transaction to the Stellar network. This is the only way to make changes "on-chain".
Unlike Horizon, this does not wait for transaction completion. It simply validates and enqueues the transaction. Clients should call Get Transaction to learn about transaction success/failure.
This supports all transactions, not only smart contract-related transactions.
Parameters

:Soroban.RPC.Server
struct - The Soroban-RPC server to interact with.base64_envelope
:<xdr.TransactionEnvelope>

The getTransactions method return a detailed list of transactions starting from the user specified starting point.
Parameters
-
server
:Soroban.RPC.Server
struct - The Soroban-RPC server to interact with. -
TransactionsPayload
:-
start_ledger
: Stringified ledger sequence number to fetch events after (inclusive). This method will return an error if start_ledger is less than the oldest ledger stored in this node, or greater than the latest ledger seen by this node. If a cursor is included in the request, start_ledger must be omitted. -
cursor
: A string ID that points to a specific location in a collection of responses and is pulled from the paging_token value of a record. When a cursor is provided Soroban-RPC will not include the element whose id matches the cursor in the response. Only elements which appear after the cursor are included. -
limit
: The maximum number of records returned. For getTransactions, this ranges from 1 to 200 and defaults to 50.

Clients can request a filtered list of events emitted by a given ledger range.
Soroban-RPC will support querying within a maximum 24 hours of recent ledgers.
Note: This could be used by the client to only prompt a refresh when there is a new ledger with relevant events. It should also be used by backend Dapp components to "ingest" events into their own database for querying and serving.
If making multiple requests, clients should deduplicate any events received, based on the event's unique id field. This prevents double-processing in the case of duplicate events being received.
By default soroban-rpc retains the most recent 24 hours of events.
Parameters
-
server
:Soroban.RPC.Server
struct - The Soroban-RPC server to interact with. -
EventsPayload
:-
start_ledger
: Stringified ledger sequence number to fetch events after (inclusive). This method will return an error if start_ledger is less than the oldest ledger stored in this node, or greater than the latest ledger seen by this node. If a cursor is included in the request, start_ledger must be omitted. -
cursor
: (optional) A string ID that points to a specific location in a collection of responses and is pulled from the paging_token value of a record. When a cursor is provided Soroban-RPC will not include the element whose id matches the cursor in the response. Only elements which appear after the cursor are included. -
limit
: (optional) The maximum number of records returned. The limit for getEvents can range from 1 to 10000 - an upper limit that is hardcoded in Soroban-RPC for performance reasons. If this argument isn't designated, it defaults to 100. -
filters
: List ofEventFilter
for the returned events. Events matching any of the filters are included. To match a filter, an event must match both a contractId and a topic. Maximum 5 filters are allowed per request.type
: (optional) A list of event types (:system
,:contract
, or:diagnostic
) used to filter events. If omitted, all event types are included.contract_ids
: (optional) List of contract ids to query for events. If omitted, return events for all contracts. Maximum 5 contract IDs are allowed per request.topics
: (optional) List ofTopicFilter
. If omitted, query for all events. If multiple filters are specified, events will be included if they match any of the filters. Maximum 5 filters are allowed per request.TopicFilter
: is a SegmentMatcher[]. The list can be 1-4 SegmentMatchers long.SegmentMatcher
:- For an exact segment match, use Soroban.ex Types that will be converted into string base64-encoded ScVal values.
- For a wildcard single-segment match, the string "*", matches exactly one segment.
- E.g:
[Symbol.new("transfer"), "*", "*", "*"]
-

In order to facilitate seamless integration with wallets, we have developed functions that enable the retrieval of the unsigned Transaction Envelope XDR for each type of interaction with contracts: invocation, upload, and deployment.
This XDR is required by wallets to sign transactions before they can be submitted to the network. Once the wallet returns the signed XDR, the Soroban.RPC.send_transaction/1
function can be used to submit the transaction.
